亞化咨詢認(rèn)為，對(duì)燃料電池催化劑相關(guān)科研單位與企業(yè)來(lái)說(shuō)，不僅需要持續(xù)對(duì)低鉑與非鉑催化劑的研發(fā)，還應(yīng)加強(qiáng)現(xiàn)有鉑催化劑的批次一致性，此外還要提早對(duì)催化劑回收再利用上做針對(duì)性的布局。2018中國(guó)燃料電池、雙極板與膜電極關(guān)鍵材料論壇將于9月19-20日在遼寧大連召開(kāi)，燃料電池催化劑鉑含量降低技術(shù)與非貴金屬催化劑將是會(huì)議探討的重要議題之一。
2018年7月10日，日本田中控股株式會(huì)社宣布，田中貴金屬工業(yè)株式會(huì)社將增設(shè)位于神奈川縣的開(kāi)發(fā)制造燃料電池用電極催化劑的燃料電池催化劑開(kāi)發(fā)中心。通過(guò)此次增設(shè)，可將目前的生產(chǎn)能力提高7倍。增設(shè)大樓預(yù)計(jì)2018年7月18日竣工，于2019年1月起正式啟用。
催化劑是質(zhì)子交換膜燃料電池（PEMFC）膜電極（MEA）的關(guān)鍵材料之一，決定了其放電性能和壽命。催化劑分為鉑催化劑、低鉑催化劑與非鉑催化劑。由于PEMFC工作溫度不足100，對(duì)催化劑活性要求很高，因此，鉑催化劑成為最理想、也是當(dāng)前唯一商業(yè)化的催化劑。
亞化咨詢《中國(guó)氫能與燃料電池年度報(bào)告2018》顯示，2017年至今中國(guó)燃料電池用催化劑研發(fā)與市場(chǎng)進(jìn)展如下。
北京大學(xué)

上海交通大學(xué)
2017年7月，上海交通大學(xué)機(jī)械與動(dòng)力工程學(xué)院燃料電池研究所章俊良教授課題組成功制備出具有單分散性的球形高活性PdxNi1-x@Pt/C核殼納米催化劑，在不損失燃料電池壽命的前提下，可大幅降低燃料電池的鉑用量。
中國(guó)科學(xué)技術(shù)大學(xué)
2017年7月，中國(guó)科學(xué)技術(shù)大學(xué)曾杰教授課題組與合作者共同設(shè)計(jì)出一種直徑僅有1.3納米的、銠原子摻雜的超細(xì)納米線鉑催化劑，鉑原子的利用率達(dá)到48.6%。研究表明，該催化劑質(zhì)量活性和比活性分別達(dá)到了商業(yè)鉑碳催化劑的7.8倍和5.4倍。同時(shí)，該催化劑在循環(huán)使用1萬(wàn)次后，僅損失了9.2%的質(zhì)量活性。
大連理工大學(xué)
2017年1月，大連理工大學(xué)化工學(xué)院能源電化學(xué)工程宋玉江教授團(tuán)隊(duì)將分子自組裝技術(shù)與高溫?zé)峤夥椒ńY(jié)合制備出一種非貴金屬電催化劑，有效提高了燃料電池電催化劑的耐久性。
亞化咨詢《中國(guó)氫能與燃料電池年度報(bào)告2018》顯示，鉑用作PEMFC催化劑存在如下三個(gè)問(wèn)題：
1）鉑資源匱乏：公開(kāi)資料顯示，全球鉑金儲(chǔ)量?jī)H1.4萬(wàn)噸；美國(guó)地質(zhì)調(diào)查局?jǐn)?shù)據(jù)顯示，2016年全球鉑產(chǎn)量?jī)H191噸；
2）價(jià)格昂貴：鉑是一種貴金屬，價(jià)格昂貴，這也使得燃料電池成本居高不下，進(jìn)而影響其商業(yè)化與推廣普及；
3）抗毒能力差：鉑基催化劑與燃料氫氣中的一氧化碳、硫等物質(zhì)發(fā)生反應(yīng)會(huì)導(dǎo)致其失去活性，無(wú)法再進(jìn)行催化作用，進(jìn)而導(dǎo)致電堆壽命縮減。
按照2016年10月，中國(guó)汽車(chē)工程學(xué)會(huì)發(fā)布的《節(jié)能與新能源汽車(chē)技術(shù)路線圖》，2030年，中國(guó)燃料電池車(chē)發(fā)展規(guī)模要達(dá)到百萬(wàn)輛，亞化咨詢假設(shè)每輛燃料電池車(chē)用鉑量為20g，則2030年中國(guó)燃料電池車(chē)鉑的需求量為20噸。但事實(shí)上，值得注意的是，鉑在催化中并未發(fā)生損耗，絕大部分可以回收再利用。
資料顯示，當(dāng)前多數(shù)燃料電池催化劑還停留在實(shí)驗(yàn)室制備水平，一般為毫克級(jí)，而量產(chǎn)技術(shù)需要公斤級(jí)甚至噸級(jí)。亞化咨詢認(rèn)為，對(duì)燃料電池催化劑相關(guān)科研單位與企業(yè)來(lái)說(shuō)，不僅需要持續(xù)對(duì)低鉑與非鉑催化劑的研發(fā)，還應(yīng)加強(qiáng)現(xiàn)有鉑催化劑的批次一致性，此外還要提早對(duì)催化劑回收再利用上做針對(duì)性的布局。

View China Fuel Cell Catalyst 5 MajorProgresses (2017-2018)
ASIACHEM believes that, to those relatedscientific research units and enterprises of fuel cell catalyst,they not only need to continue R&D on low-Pt and non-Ptcatalyst, but also need to strengthen batch consistency of currentPt catalyst. Besides, they should do targeting distribution onrecycling of catalyst in advance. Fuel Cells, BipolarPlate & MEA Key Materials Forum 2018 will be held in Dalian,Liaoning on Sep 19-20, and Catalyst> will beone of key issues discussed in the meeting.
Jul10, 2018, Japan Tanaka Kikinzoku Group announced that, TanakaKikinzoku Kogyo K.K. will new increase a Fuel Cell CatalystDevelopment Center in Kanagawa to develop and manufacture fuel cellused electrode catalyst. Through this Center, Tanaka KikinzokuKogyo K.K. will increase 7 times of its current capacity. TheCenter is estimated to finish construction on Jul 18, 2018, andformally starts to use from Jan 2019.
Catalyst is one of key materials of membraneelectrode assembly of proton exchange membrane fuel cell (PEMFC)and which decides discharging characteristics and lives of PEMFC.Catalyst is mainly divided into platinum (Pt) catalyst, low-Ptcatalyst and non-Pt catalyst. Working temperature of PEMFC is lessthan 100,which has high requirement to activity of catalyst. Thus, Ptcatalyst becomes the most ideal, and the only catalyst thatrealizes commercialization.
ASIACHEM shows that, from 2017 till now,China fuel cell used catalyst R&D and marketing progresses areas below.
Peking University
In Jun2018, GUO Shaojun team of College of Engineering,Peking University developed a new dumbbell shaped PtFe-Fe2Cnano-particles. The catalyst specific activity and mass activity ofoxygen reduction reaction under acid medium reach 353mA/cm2 and1.50A/mg, respectively, and which are 11.8 times and 7.1 timeshigher than the commercialized Pt catalyst. Besides, it has veryexcellent electrochemical stability, after 5000 cycles, activity ofcatalyst almost has no deduction.
Wuhan Himalaya Optoelectronics Technology Co.Ltd.
In Apr2018, fuel cell Pt/C catalyst mass production technology, which isindependently R&D by Wuhan Himalaya, made breakthroughs.Information shows that, the catalyst uses catalyst preparationtechnology of Tsinghua University. Technical breakthroughsinclude:
1. Using continuous synthesis process, realizesproduct characteristics’ high consistency and each index can becontrolled within ±1%;
2.Capacity reaches scale of 1200g/d, which can satisfy 40 36kW fuelcell stacks, and has industrialization production and marketingrequired each condition;
3.Using optimized carrier treatment process, carrier cycle lifereaches more than 5 times of international commercial used catalystof same kind, and extremely increase catalyst using life undervehicle used working condition;
4.Catalyst comprehensive performance (polarization, electrochemicalactive area and mass specific activity) reaches or exceedsinternational commercial used catalyst of samekind;
5.Serial catalyst products passed examine of Tsinghua UniversityAnalysis Center and EU CE authentication, each performance indexmeets designed requirement;
Massproduction Pt/C catalyst mainly includes 40wt%, 50wt%, 60wt% and70wt% specs and has advantages of high activity, high stability andlow cost.
Shanghai Jiao TongUniversity
In Jul2017, Prof ZHANG Junliang project team of Shanghai Jiao TongUniversity School of Mechanical Engineering Fuel Cell ResearchInstitute successfully prepared spherical high activityPdxNi1-x@Pt/C coreshelled nano catalyst which has mono-dispersion. Under premise ofnot losing life of fuel cell, it can greatly reduce Pt usage offuel cell.
University of Science and Technology ofChina
In Jul2017, Prof ZHANG Jie project team of University of Science andTechnology of China and partner co-designed an ultra-fine nanowirePt catalyst which diameter is only 1.3nm and doped with atomicatom, and which availability of Pt atom reaches 48.6%. The Researchindicates that, mass activity and specific activity of thiscatalyst reach 7.8 times and 5.4 times of commercialized Pt/Ccatalyst. Meanwhile, this catalyst only loses 9.2% mass activityafter recycling 10000 times.
Dalian University ofTechnology
In Jan2017, Prof. SONG Yujiang team of Dalian University of TechnologyChemical School Energy and Electrochemical Engineering combinedmolecular self-assembly technology and high temperature pyrolysismethod and prepared a non-noble metal electrocatalyst, andeffectively increased durability of fuel cellelectrocatalyst.
ASIACHEM shows that, Pt beingas catalyst of PEMFC has 3 problems below:
1) Ptresources are lack: Public information shows that global Ptreserves are only 14kt; US Geological Survey (USGS)data shows that in 2016, global Pt output wasonly 191t;
2)Price is high: Pt is a noble metal, and its price is high, whichfurther makes fuel cell cost stay in a high position and influencesits commercialization and popularization.
3)Toxin resistance is weak: Pt catalyst react with CO, S etc.substances in fuel hydrogen will make it lose activity and cannotplay catalytic action any longer, and further lead stack lifereduce.
According to released by SAE-China in Oct 2016,in 2030, China fuel cell vehicle development size should reachmillions. ASIACHEM assumes each fuel cell vehicle Pt usage is 20g,then in2030, China fuel cell vehicle Pt requirement will be20t. However, which isnoteworthy that, Pt does not have any losses during catalyzing andmost Pt can be recycled.
Information shows that, currently, most fuelcell catalyst are still staying at laboratory preparation level,which also milligram level, mass production technology, however, iskilogram level or even ton level. ASIACHEM believes that, to thoserelated scientific research units and enterprises of fuel cellcatalyst, they not only need to continue R&D on low-Pt andnon-Pt catalyst, but also need to strengthen batch consistency ofcurrent Pt catalyst. Besides, they should do targeting distributionon recycling of catalyst in advance.
ASIACHEM launched in May 2018, will discusscontents below:
1. Global and ChinaHydrogen Energy and Fuel Cell Industrial Chain Development Prospectand Investment Opportunities
2. Hydrogen ProductionTechnologies and Cost Analysis – Water Electrolysis, Natural GasSMR, Methanol Cracking and Coal Gasification
