摘　　要：根据储氢系统可能达到的比能量和燃料电池堆在常温常压下的比功率讨论了小功率氢 空气燃料电池系统的比能量 ,在连续工作时间不长时难以与常规二次电池竞争。在常温下如何排除电池反应生成的水也存在一些问题。据此讨论了小功率氢The energy density of small power hydrogen air fuel cell systems was discussed by considering the practically available energy density of the hydrogen storage system and the power density of fuel cell stacks at room temperature and atmospheric pressure.The energy density of small power fuel cell systems was found to be lower than that of the conventional secondary batteries if the working time of the power system was not sufficient long.The removal of water produced in cell reaction also became a problem at room temperature.The possible applications of small power hydrogen air fuel cell and the main problems to be solved were discussed.
