New harmonized test protocols for PEM fuel cells in hydrogen vehicles

(European Commission Joint Research Centre) A lack of standards for testing polymer electrolyte membrane (PEM) fuel cells -- the most attractive type of fuel cells for powering vehicles -- has hampered objective comparative assessment of their performance and durability under operating conditions and hence of their technological progress. By proposing a test methodology including a set of representative operating conditions and getting European industry and research stakeholders to agree on it, ...
