All the mathematic models of PEM-FC balanced response have been established according to the Butler-Volmer model of electrode kinetics with numeric approach. To support the interaction between grid side and user side, a PEM-FC controlling device is designed as DSM user agent to provide gird-connected function. The Boost circuit and associated battery energy management system (BEMS) are considered together with temperature effect. It is proved that the porous characteristic of the backing materials facilitates reactant gas diffusion to the catalyst on membrane electrode assembly and it can be regarded as electrical connection between carbon-supported catalyst and the plate during DSM program.
