摘要

This work is focused on the fabrication of membrane electrode assembly (MEA) and power performances by applying carbon supported metal phthalocyanine (MPc/C, M = Co, Cu, Zn, Ni) as cathode catalysts for alkaline anion exchange membrane fuel cells. The MPc/C catalysts are synthesized via a combined solvent-impregnation along with the different temperature treatment. The catalytic activity of MPc/C catalysts toward ORR are screened by linear sweep voltammetry (LSV) employing a rotating disk electrode (RDE) technique. The MEA fabricated with MPc/C catalysts and the Tukuyama membrane gave the initial power densities of 12.6, 6.8, 6.1 and 6.0 mW cm~(-2) for CoPc/C, CuPc/C, NiPc/C and ZnPc/C, respectively, at room temperature using H_2 and O_2 gas. At this stage, the power densities of MPc/C catalysts with Cu, Ni and Zn as centre metals are still low in comparison with that of CoPc/C, however, these initial results are promising for the application both in alkaline membrane fuel cells and metal-air batteries by further optimization of MEA preparation and cell test conditions.
