Influence of SO2 Concentration and Relative Humidity on Electrode Poisoning in Polymer Electrolyte Membrane Fuel Cells

Influence of SO2 Concentration and Relative Humidity on Electrode Poisoning in Polymer Electrolyte Membrane Fuel Cells

We investigated influences of SO2 concentration and relative humidity in fuel and air streams on anode and cathode poisoning behaviors under open circuit voltage and load operating conditions in polymer electrolyte membrane fuel cells (PEMFCs). The rate of cell voltage degradation increased with the...
