Solid oxide fuel cells (SOFCs) are energy conversion devices which directly convert chemical energy in a fuel to electrical power through electrochemical reactions over their electrodes.However,one important limitation is the lack of a high-performance cathode that can reserve high oxygen reduction activity as temperature decreased.

本文重点对通信基站用燃料电池备用电源系统的氢气供应方案进行了分析并对不同方案的系统成本进行了比较。针对高压运输方案还提出了基于遗传算法的运输路径优化方法,以实现降低高压运输方案时的成本。通过对特定区域的供氢方案分析初步得出以下结论:燃料电池备用电源通信基站以高压气态运输方式进行氢气供应的方案其年平均投入成本在现阶段为最低,是目前较为合适的通信基站备用能源解决方案。
催化剂载体是燃料电池的重要组成部分,主要起到固定催化剂和辅助催化剂保持大的活性表面积,更重要的是防止催化剂在反应过程中发生聚合等作用.当前,燃料电池主要使用碳黑作为催化剂载体材料,然而在实际操作中碳黑易被腐蚀或氧化而导致催化剂失效.这是长期以来阻碍燃料电池普遍应用的核心问题之一.过渡金属氮化物(TMN)具有高耐腐蚀性,高导电性.我们的研究发现介孔氮化物材料与一般块体氮化物材料在化学性质上,尤其是作
