The performance of a novel carbon-supported copper complex of 3,5-diamino-1,2,4-triazole (Cu-tri/C) is investigated as a cathode material using an alkaline microfluidic H(2)/O(2) fuel cell. The absolute Cu-tri/C cathode performance is comparable to that of a Pt/C cathode. Furthermore, at a commercially relevant potential, the measured mass activity of an unoptimized Cu-tri/C-based cathode was significantly greater than that of similar Pt/C- and Ag/C-based cathodes. Accelerated cathode durability studies suggested multiple degradation regimes at various time scales. Further enhancements in performance and durability may be realized by optimizing catalyst and electrode preparation procedures.
采用碱性微流体 H(2)/O(2)燃料电池，研究了新型 3,5-二氨基-1,2,4-三唑（Cu-tri/C）负载碳复合物作为阴极材料的性能。Cu-tri/C 阴极的绝对性能可与 Pt/C 阴极相媲美。此外，在具有商业相关性的电位下，未经优化的基于 Cu-tri/C 的阴极的实测质量活度明显大于类似的 Pt/C-和 Ag/C-基阴极的质量活度。加速的阴极耐久性研究表明，在不同时间尺度下存在多种降解机制。通过优化催化剂和电极制备程序，可能会进一步提高性能和耐久性。
