摘　　要：分析了燃料电池效率的极限值,从理论上阐明了其值随反应温度的升高而降低,从而得出了燃料电池的最大理论效率.分析了高温燃料电池 热机联合循环,得出了其最大理论效率,从理论上说明了高温燃料电池 热机联合循环可将燃料的化学能高效地转变为电能.The efficiency limit of the fuel cell is analyzed. It is obtained that the efficiency limit decreases with the increase of temperature. The maximum theoretical efficiency is then obtained. Then, hightemperature fuel cellheat engine combined cycle is analyzed, and its maximum theoretical efficiency is obtained, whereby it is explained that hightemperature fuel cellheat engine combined cycle can be used to efficiently transform chemical energy of combustible into electric energy.
