Description
Summary:Cold-start (subzero startup) capability of polymer electrolyte fuel cell (PEFCs) is of great importance to achieve the commercialization of the fuel cell. In this paper, the effect of micro porous layer (MPL) on the cell performance is investigated not only in the normal condition but also at subzero temperature. The effect of startup current density variation on the cold start operation is considered. The anode and cathode pressure revolution of PEFC act as a great tool to understand the effect of MPL on the liquid-water removal. It is also found that PEFCs with anode micro-porous-layer (AMPL), compared with one with CMPL, have superior cold start performance due to the voltage reverse phenomenon.
