Design and Simulation on Polymer Electrolyte Membrane Fuel Cell Bipolar Plates with Hilbert Patterns

Abstract:

Polymer Electrolyte Membrane fuel cell converts directly electrochemical energy into electricity. Channels in bipolar Plate, a critical component of fuel cell, is designed with Hilbert pattern, which are obtained through offsetting Hilbert curves to both sides according to working size. Polarization curve expresses the same characteristics between Hilbert channel and traditional serpentine and parallel channel. Output current densities of Hilbert channel are equivalent to that of the serpentine channel but larger than that of parallel channel. Simulation demonstrates that fluid flowing states in Hilbert channel are similar to that in serpentine channel and investigates that pressure drop changes with composite Hilbert channel arrangement. Temperature is an important factor influencing fuel cell performance and optimal temperature is close to 333K in this research.
