报道了一种采用氢氧离子导电膜的直接甲醇燃料电池（DMFC）的研究。使用膜电极组件进行燃料电池的评价，该膜电极组件包括碳支撑的铂/钌阳极和铂阴极催化剂以及ADP碱性膜。阳极和阴极所用的催化剂负载量均为1 mgcm-2 Pt。报道了温度、氧化剂（空气或氧气）和甲醇浓度对电池性能的影响。该电池在60°C下使用氧气时达到了16 mWcm −2的功率密度。在接近环境条件下的空气性能给出了约6 mWcm −2的峰值功率密度。
A study of a direct methanol fuel cell (DMFC) operating with hydroxide ion conducting membranes is reported. Evaluation of the fuel cell was performed using membrane electrode assemblies incorporating carbon-supported platinum/ruthenium anode and platinum cathode catalysts and ADP alkaline membranes. Catalyst loadings used were 1mgcm−2Pt for both anode and cathode. The effect of temperature, oxidant (air or oxygen) and methanol concentration on cell performance is reported. The cell achieved a power density of 16mWcm−2, at 60°C using oxygen. The performance under near ambient conditions with air gave a peak power density of approximately 6mWcm−2.
