Research Progress of Proton Exchange Membrane Fuel Cells with Metal-Foam Flow Fields
Metal-foam is a novel multifunctional material with exceptional properties,including high porosity,high electrical conductivity,good heat transfer ability,and low weight.Embedding metal-foam as flow fields in proton exchange membrane fuel cell(PEMFC)is gaining increasing attention in recent years.This paper reviews the latest research progress on PEMFC flow fields,investigates the impact of metal-foam structural parameters,flow field design,and environmental factors on the performance of PEMFC in terms of power density,gas distribution,pressure drop,and water-and-heat management.Furthermore,the corrosion and flooding problems faced by metal-foam flow fields in PEMFC applications are discussed,and the research advancements made on metal-foam with corrosion-resistant coatings are highlighted.This work provides useful insights for developing and optimizing PEMFC metal-foam flow fields,and expects to deliver implications for advancing metal foam applications in PEMFCs.
