ABSTRACTThe current major cost component for proton exchange membrane fuel cells is the bipolar plate. An option being explored for replacing the current, nominal machined graphite component is a molded carbon fiber material. One face and the volume of the component will be left porous, while the opposite surface and sides are hermetically sealed via chemical vapor infiltration of carbon. This paper will address initial work on the concept.

A new high performance, low cost heterogeneous composite bipolar plate has been developed. Unlike the well publicized carbon composite bipolar plate, in which graphite powder and plastics are mixed thoroughly, the new plate has its “ribs” made of flexible and loose carbon fiber bunches while the rest of the plate is plain plastic. This design has brought many advantages: low contact resistance acquired under very low compression force, less stack weight and volume, full electrode utilization, and thus high performance and low cost. It also eliminates the need for supplementary devices for fuel circulation among cells in a stack and makes DMFC portable.

ABSTRACTA carbon composite bipolar plate for PEM fuel cells has been developed that has high electrical conductivity, high strength, light weight, is impermeable, and has the potential for being produced at low cost. The plate is produced by slurry molding short carbon fibers into preform structures, molding features into the green body, and using chemical vapor infiltration to strengthen the material, give it high conductivity, and densify the surface to make it impermeable. Current efforts have focused on optimizing the fabrication process and characterizing prototypical components.

In this present work, finite volume method was used to simulate the three-dimensional water flow and heat transfer in a flow field plate of the proton exchange membrane (PEM) electrolysis cell. The standard k-ε model together with standard wall function method was used to model three-dimensional fluid flow and heat transfer. First, numerical simulations were performed for a basic bipolar plate and it was found that the flow distribution inside the channels in not uniform. The design of the basic bipolar plate has been changed to a new model, which is featured with multiple inlets and multiple outlets. Numerical results show that the flow and temperature distributions for the new design become much homogeneous.
