In-Situ Measurement of Oxygen Partial Pressure in the Cathode Flow Field with a Hydrophilic Surface

Cathode oxygen concentration is vital for the performance of proton exchange membrane fuel cells (PEMFC). A novel method to directly detect oxygen partial pressure in the cathode flowfield has been developed utilizing fluorophore molecules which are sensitive to oxygen quenching. A platinum porphyri...
