Description
| - Gas diffusion electrodes (GDEs) were prepared and optimized for testing a novel electrolyte for PEM-type fuel cells operating at elevated temperatures based on polymer-supported ionic liquid (IL). For the construction of the GDE, a commercial E-TEK gas diffusion layer was employed. On its surface, a catalyst layer (CL) was deposited by the brushing technique. The catalyst ink contained a commercial, carbon-supported platinum catalyst (30 wt.% ? E-TEK), polymer binder and solvents. As a binder, polytetrafluoroethylene (PTFE) or polybenzimidazole (PBI) was applied. Various amounts of binder were used in the CL. The utilization of PBI was found to be more advantageous than PTFE. 15 wt.% PBI was identified as the optimum amount in the CL. Such electrodes exhibit a relatively good performance in a laboratory-scale single fuel cell employing commercial PBI?based membranes doped by H3PO4 (50 mW/cm2 at 0.4 V and 140 °C). Although polymer-supported IL-based membranes exhibit relatively high ionic conductivity,
