Nitrogen doped carbon nanotubes (N-CNTs) with different nitrogen contents were synthesized as non-precious catalysts for oxygen reduction reaction (ORR) through varying the relative amount of pyridine and ethanol in the stock solution. The structural and chemical properties of the N-CNTs were invest
## Abstract Water content in the membrane and the presence of liquid water in the catalyst layers (CL) and the gas diffusion layers (GDL) play a very important role in the performance of a PEM fuel cell. To study water transport in a PEM fuel cell, a twoโphase flow mathematical model is developed.
The effect of carbonate and bicarbonate anions on the oxygen reduction reaction was investigated in four alkaline solutions (pH โผ 14) on a Pt disk type electrode with varying concentrations of carbonate and bicarbonate. The addition of carbonate and bicarbonate had two primary effects on the observe
