Electrochemical cells based on acid salts (CsHPO) have attracted great interest for intermediate temperature, due to the outstanding proton conductivity of acid salts. In this work, electrodes and electrolyte were optimized following different strategies. An epoxy resin was added to the CsHPO material to enhance the mechanical properties of the electrolyte, achieving good conductivity, enhanced stability, and cyclability. The electrodes configuration was modified, and Ni sponge was selected as active support. The infiltration of different oxide nanoparticles was carried out to tailor the electrodes resistance by promoting the electrocatalyst activity of electrodes. The selection of a cell supported on the electrode and the addition of an epoxy resin enables the reduction of the electrolyte thickness without damaging the mechanical stability of the thinner electrolyte.
基于酸盐（CsHPO）的电化学电池因其酸盐出色的质子传导性而在中温领域引起了极大关注。在这项工作中，电极和电解质按照不同策略进行了优化。向CsHPO材料中添加了环氧树脂以增强电解质的机械性能，实现了良好的导电性、增强的稳定性和循环性。对电极结构进行了改进，并选择镍海绵作为活性载体。通过促进电极的电催化活性来进行不同氧化物纳米颗粒的浸润，以调整电极电阻。选择基于电极支撑的电池并添加环氧树脂能够在不损害更薄电解质机械稳定性的情况下减小电解质厚度。
