長時間駆動が可能な次世代型小型電源として、直接ギ酸形燃料電池（DFAFC）に注目した。DFAFCは直接形燃料電池の中では出力が高いため、小型化が可能であるが、時間の経過に伴い出力が低下する。そこで本研究では、空気極由来の出力低下の抑制が可能な新規電極構造体と燃料極由来の出力低下の抑制が可能な新規触媒をDFAFCに適用することで、DFAFCの出力低下の抑制に取り組んだ。その結果、空気極由来の出力低下抑制に成功した。また、作製した触媒は高い被毒耐性を示すが、セルでの出力が低いため、本触媒に適した新たな設計指針を構築する必要が有ることがわかった。
We focused on the direct formic acid fuel cell as promising portable electric power generation devices which can operate for a long time. The power density of the DFAFC decreases with the time although the its initial power density is high. In this study, the novel electrode structure which can inhibit the performance decay due to the cathode, and the novel catalyst which can inhibit the poisoning of the anode catalyst were develop to prevent the performance decay of the DFAFC. The performance decay due to the cathode electrode could be successfully inhibited by the novel electrode structure. Regarding on the developed novel catalyst, it showed high resistance for the catalyst poisonings, however, it was found that the improvement for the cell fabrication method using this catalyst is required since the cell performance using developed catalyst was low.
