将环己烷、甲基环己烷、环己烯、异丙醇、环己醇等一系列“有机化合物”应用于直接质子交换膜燃料电池。以环己烷（OCV = 920 mV，PD（max）= 15 mW cm（-2））和异丙醇（OCV = 790 mV，PD（max）= 78 mW cm（-2））为燃料，实现了高性能的PEM燃料电池，且没有CO2排放。估算了环己烷、异丙醇和甲醇的燃料渗透速率，环己烷和异丙醇的燃料渗透速率低于甲醇的燃料渗透速率。对质子交换膜介导的水电解和丙酮电还原加氢反应进行了研究，观察到阴极侧有异丙醇生成。该系统是“可再充电”直接燃料电池的第一个例子。
A series of "organic chemical hydrides" such as cyclohexane, methylcyclohexane, cyclohexene, 2-propanol, and cyclohexanol were applied to the direct PEM fuel cell. High performances of the PEM fuel cell were achieved by using cyclohexane (OCV = 920 mV, PD(max) = 15 mW cm(-2)) and 2-propanol (OCV = 790 mV, PD(max) = 78 mW cm(-2)) as fuels without CO(2) emissions. The rates of fuel crossover for cyclohexane, 2-propanol, and methanol were estimated, and the rates of fuel permeation of cyclohexane and 2-propanol were lower than that of methanol. Water electrolysis and electro-reductive hydrogenation of acetone mediated by PEM were carried out and formation of 2-propanol in cathode side was observed. This system is the first example of a "rechargeable" direct fuel cell.
