✦ Synopsis

An analysis of leakage currents in bipolar systems is carried out, using an equivalent circuit approach. The resulting non-linear difference equations appropriate to the Tafel regime are solved by four different methods: (a) piecewise linear method (PLM), (b) iterative piecewise linear method (IPLM), (c) Adomian decomposition method (ADM), and (d) Piecewise linear continuum (PLC). On the basis of the numerical analysis, it is seen that PLM is a good approximation, and IPLM as well as ADM converge rapidly to the true values. These results are also compared with a continuum version.

## Abstract Polymer electrolyte fuel cell systems are increasingly being used in applications requiring an inverter to convert the direct current (DC) output of the stack to an alternating current (AC). These inverters, and other time‐varying inputs to the stack such as the anode feed pressure, cau
