Improved Electrode Performance Using Fine-Tuned Poly(arylene piperidinium) Ionomers In Anion Exchange Membrane Fuel Cells
Ionomers based on poly(arylene piperidinium)s with varying ion exchange capacities are evaluated in different combinations of anode and cathode electrodes in anion exchange membrane fuel cells. The operational conditions are chosen with an asymmetrical regime including a dry anode with 50% relative humidity at the inlet, and full humidification at the cathode.
