ダイレクトメタノール燃料電池（DMFC）の開発状況と技術課題

抄録

Recently a fuel cell system that is clean and efficient has been expected as an on-site, mobile and/or vehicles power source. These days, a research and development of direct methanol fuel cell (DMFC) has been extending in various fields, such as catalysis, electrolytes, electrode structure and fuel cell engineering. The DMFC technologies are similar to those of polymer electrolyte fuel cell (PEFC), however, there are serious technical issues such as methanol cross-leak and lower anode catalyst activity. In this paper, recent progress and technical issues of DMFC will be explained with our experimental result.
