Determination of an Optimum Performance of a PEM Fuel Cell Based on its Limiting Current Density,ent density, ohmic resistance and K. The results showed that higher overpotentials and optimum current densities are achieved with higher values of A, B, ohmic resistance or limiting current density. Furthermore, higher activation overpotential and optimum cell voltage can be achieved with an increase in K.

Oxygen Source for Isolated Fuel Cells,ly blocked by a closure formed of pliable rubber like material that is forced against the passageway leading from the manifold to the cell by higher gas pressure in the manifold, which occurs when the pressure becomes lower in the given cell due to a leak.
