Modeling and simulation of PEM fuel cell based on distributed-parameter model

The study of the dynamic modeling of PEM fuel cell was based on the distributed-parameter model. The simulation will complete with Fluent, a computer software dealing with the PEM module of computer fluid dynamics. This paper first describes the distributed-parameter model, including the quality, momentum, energy, species conservation equation in PEM cell, the electrical chemistry equation in the catalyst layer, then a 3D structure model for single cell with a single channel is established. The dynamic response and performance were calculated with the non-steady calculator in Fluent. Simulations are that dynamic responses of voltage when current density step changes.
