Pt-Ru 触媒を用いたジメチルエーテル燃料電池の性能

概要

論文の詳細を見る
Phenomena is presented whereby the performance of a dimethyl-ether fuel cell (DDFC) at 80°C is much lower when Pt-Ru catalyst is used on the anode than when Pt catalyst is used, in contrast to the higher performance achieved using Pt-Ru catalyst over Pt catalyst in direct methanol fuel cells (DMFC). The DDFC performance achieved using Pt-Ru catalyst increases with temperature and exceeds that using Pt catalyst at temperatures of over 100°C. After high temperature operation, the performance of DDFC using Pt-Ru catalyst at 80°C is improved. By supplying sufficient steam before operation, the performance of DDFC using Pt-Ru catalyst at 80°C is also found to improve. Before and during operation, more steam is needed for stable operation of the DDFC using Pt-Ru catalyst at 80°C than using Pt catalyst.
