论文摘要
基于氢的燃料需要高密度存储，该存储可以在环境温度下运行。 PD及其合金是用于氢燃料电池应用最多的金属氢化物。这项研究提出了一种用于氢存储的替代PD合金，可以在室温下存储和释放氢。研究最多的PD（110）的表面通过AU和RH进行了修饰，因此氢吸附能为0.49 eV，释放温度为365K。这两个值都接近了现实使用中氢燃料电池的吸附能和释放温度的最佳值。
Hydrogen-based fuels demand high-density storage that can operate under ambient temperatures. Pd and its alloys are the most investigated metal hydrides for hydrogen fuel cell applications. This study presented an alternative Pd alloy for hydrogen storage that can store and release hydrogen at room temperature. The surface of the most studied Pd (110) was modified with Au and Rh so that the hydrogen adsorption energy was 0.49 eV and the release temperature was 365 K. Both values are quite near to the optimum values for the adsorption energy and release temperature of a hydrogen fuel cell in real-world usage.
