固体酸燃料电池(SAFCs)具有不渗透燃料、较高电极催化活性和抗一氧化碳中毒的特点,作为燃料电池领域一个崭新的研究方向,具有良好的发展前景。本文概述了固体酸燃料电池的发展背景及目前的研究状况,较详细地介绍分析以固体酸为电解质膜的燃料电池反应机理及其研究进展,展望了固体酸燃料电池的发展前景,提出了固体酸燃料电池能得以应用必须解决的一些瓶颈因素。
There is an increasing interest in a novel type of fuel cells, the solid-acid fuel cells (SAFCs), which are characterized by impermeability to fuels of the electrolyte, high electrocatalytie activity and high CO tolerance of the electrodes. This paper gives a thorough review on the background and recent progress on SAFCs. The operation principle is described in detail. The key problems for the application of SAFCs are suggested and the possible solutions are proposed.
