| Résumé | In this paper the operational and architectural flexibilities of a membraneless direct liquid fuel cell were demonstrated under aerobic and anaerobic configurations at 60 C and 1 atm. The aerobic membraneless direct methanol fuel cell (DMFC) was fed an anolyte solution of 1 MCH3OH/0.5 MH2SO4 and an air oxidant. The anaerobic membraneless direct methanol redox fuel cell (DMRFC) was fed an anolyte solution of 1 M CH3OH/0.1 M HClO4 and a catholyte solution of 2 M Fe(ClO4)3 and 0.22 M Fe(ClO4)2 oxidant. For both cases the membraneless architecture performed significantly better than for the conventional PEM architecture with Nafion 117. The maximum power density for the membraneless and Nafion 117 based DMFC was 52 mW cm 2 and 41 mW cm 2 respectively. The maximum power density for the membraneless and Nafion 117 based DMRFC was 46mW cm 2 and 34mW cm 2 respectively. In addition, anaerobic operation using a Fe2 /Fe3 catholyte gave similar performance to that for air as an oxidant. Both membraneless and anaerobic operation can result in significant cost reduction with improved operational flexibility. |
