Cell Performance of ABPBI-Based High Temperature PEM Fuel Cells


Article Preview

In this work, the cell performance of high temperature PEM fuel cells based on ABPBI membranes was experimentally measured in details. The ABPBI-based high PEM fuel cell was fabricated by using ABPBI-based gas diffusion electrodewith directly adding carbon-supported- catalyst to a homogeneous ABPBI solution prior to deposition and its membrane electrode assembly. The effects of various Pt loading of the catalyst layer, as well as the effect of different operating conditions were studied. The cell performance was evaluated using dry hydrogen/oxygen gases, which added advantage of eliminating the complicated humidification system of nafion cells. The measured results reveal that a catalyst layer with the higher Pt loading has a higher cell performance. In addition, better cell performance is noted for a case with higher cell temperature or higher cathode flowrate.
