PEM Fuelcell


For Protonex, Inc.

Protonex, a manufacturer of small PEM fuel cells for military and commercial mobile and stationary applications contracted with DBA to assist them in improving the durability of their product. The military had made its purchase of the Protonex product contingent on it meeting these new, longer life requirements. The DBA team brought to bear complex, sophisticated state-of-the-art multi-physics and CFD modeling techniques developed and calibrated over many years both by DBA staff and its academic partner. As a result specific moisture content maps, together with temperature and conductivity maps superimposed across the full fuel cell flow field for various operating conditions allowed Protonex to efficiently identify a set of operating parameters that would help them achieve their required goal of longer life.
