Abstract

A proton-conducting solid acid fuel cell (SAFC) is studied for the direct conversion of ammonia. The SAFC is supported by an electrolyte consisting of cesium dihydrogen phosphate (CsH₂PO₄) and titanium dioxide (TiO₂) to improve stability and proton conductivity. The effect of electrolyte composition, anode catalyst, and moisture on the cell performance is investigated. The result shows that the SAFC containing the CsH₂PO₄–TiO₂ (8:2) composite electrolyte and a Pt/TiO₂–Pt/C anode has the optimum power density of 1.20 and 0.64 mWcm⁻² in H₂ and NH₃ at 230°C, respectively. Electrical performance could be stabilized by prolonged exposure to moisture and further improved by the use of a thinner electrolyte.

探索一种用于氨直接转化的固体酸燃料电池

研究了一种用于氨直接转化的质子传导固体酸燃料电池（SAFC）。SAFC由磷酸二氢铯（CsH2PO4）和二氧化钛（TiO2）组成的电解质支撑，以提高稳定性和质子导电性。研究了电解液组成、阳极催化剂和水分对电池性能的影响。结果表明，含CsH2PO4-TiO2（8:2）复合电解质和Pt/ TiO2-Pt /C阳极的SAFC在H2和NH3中的最佳功率密度分别为1.20和0.64 mWcm−2。电性能可以通过长时间暴露在湿气中来稳定，并通过使用更薄的电解质进一步改善。

期刊介绍： This journal is only available online from 2011 onwards. Fuel Cells — From Fundamentals to Systems publishes on all aspects of fuel cells, ranging from their molecular basis to their applications in systems such as power plants, road vehicles and power sources in portables. Fuel Cells is a platform for scientific exchange in a diverse interdisciplinary field. All related work in -chemistry- materials science- physics- chemical engineering- electrical engineering- mechanical engineering- is included. Fuel Cells—From Fundamentals to Systems has an International Editorial Board and Editorial Advisory Board, with each Editor being a renowned expert representing a key discipline in the field from either a distinguished academic institution or one of the globally leading companies. Fuel Cells—From Fundamentals to Systems is designed to meet the needs of scientists and engineers who are actively working in the field. Until now, information on materials, stack technology and system approaches has been dispersed over a number of traditional scientific journals dedicated to classical disciplines such as electrochemistry, materials science or power technology. Fuel Cells—From Fundamentals to Systems concentrates on the publication of peer-reviewed original research papers and reviews.
