The limited use of low temperature waste heat turns thermocells into attractive devices for micropower generation. In this work, a thermocell based on a proton exchange membrane with hydrogen electrodes was experimentally investigated. The dependence of the Open Circuit Voltage on the water vapor content in hydrogen as indicated by the humidifier temperature and on the applied temperature difference between anode and cathode were studied. A maximum OCV is reported at a humidifier temperature of $300\text{K}$, whereas the maximum power density of $45.3\mathrm{\mu }\text{W}/{\text{cm}}^2$ was obtained at a humidification temperature of $323\text{K}$. For the same case and a temperature difference of $35\text{K}$ a Seebeck coefficient of 1.75 $\text{mV}/\text{K}$ was obtained. The experimental values were then compared to a thermocell model, which has already been published, based on Non-Equilibrium Thermodynamics and classical coefficients from literature.

低温余热的有限使用使热电池成为吸引人的微发电设备。在这项工作中，实验研究了基于带有氢电极的质子交换膜的热电池。研究了加湿器温度指示的开路电压对氢气中水蒸气含量的依赖性以及阳极与阴极之间施加的温差的依赖性。据报道，加湿器温度为10摄氏度时，最大OCV$300\text{ķ}$，而最大功率密度为 $45.3\mathrm{\mu }\text{w ^}/{\text{厘米}}^2$ 是在加湿温度为 $323\text{ķ}$。对于相同的情况和温差为$35\text{ķ}$ 塞贝克系数为1.75 $\text{毫伏}/\text{ķ}$获得了。然后根据非平衡热力学和文献中的经典系数，将实验值与已发布的热室模型进行比较。
