Performance losses at H2/O2alkaline membrane fuel cell

Performance losses at H2/O2alkaline membrane fuel cell. Khadke, P. S. & Krewer, U. Electrochemistry Communications, 51:117–120, February, 2015.

Paper doi abstract bibtex

H2/O2alkaline membrane fuel cell (AMFC) is evaluated by polarization curves and conductivity measurements to determine the performance limiting factors. The analysis of IR corrected polarization curves shows that at medium to high current region significant potential loss in AMFC is caused by low ionic conductivity of membrane and catalyst layer, and limitations from mass transport of water. In low to medium current region the severe performance loss is caused by low water concentration at catalyst surface due to insufficient water concentration in the fully humidified oxidant at ≤ 60°C.
