Coated Aluminium Electrode Plates for Air Cooled (AC) PEMFC Stacks - CAEPAC

CAEPAC will establish the feasibility of coated electrode plates of lightweight alloy substrates for PEM (ProtonExchange Membrane) fuel cells. PEM fuel cells display the highest power densities of any of the fuel cell types,which makes them particularly attractive for transportation & portable applications where minimum size andweight are required. Air cooled fuel cells significantly reduce balance-of-plant complexity, hence weight (andcost), making Intelligent Energy’s AC (Air Cooled) technology particularly suitable for lower power automotiveapplications such as primary and range extender drives for lightweight vehicles. Conventional PEM fuel cellsutilise electrode plates which are made from graphite (bulky and expensive to machine) or, particularly fortransport, stainless steel. For automotive applications, 100s of cells are needed within a multi-kW stack, hencea relatively small weight saving per plate will be significant for the whole system, provided such componentscan be manufactured cheaply and with similar performance and longevity. CAEPAC will develop novel, coatedlighweight alloy plates, and investigate their performance in cells & stacks, with detailed post-mortem analysis.
