燃料电池阴极氧还原非铂类催化剂研究进展

Research progress of cathodic oxygen reduction non-platinum catalyst for fuel cell

燃料电池是一种能将化学能直接转化为电能的装置,具有对环境友好,能量转化率高等优点。目前,燃料电池主要以铂基催化剂为主,但铂价格昂贵,储量有限,易中毒,其商业化应用受到限制,因此开发低廉高效、来源广泛的非贵金属阴极氧还原催化剂成为研究热点。介绍了燃料电池阴极氧还原非铂类催化剂研究进展。

Fuel cell is a device that directly converts chemical energy into electrical energy. It has the advantages of being environmentally friendly,and having a high conversion rate. At present,platinum-based catalysts are mainly used.However,due to the high price of platinum,easy poisoning and limited reserves,it has become an obstacle to its commercialization. Thus it has been a hot topic to develop low-cost,highly resource-rich non-precious metal cathode oxygen reduction catalysts. Based on price,cost and performance considerations,the research progress of cathode oxygen reduction nonplatinum catalysts for fuel cells was described.
