Hydrogen fuel cell vehicle company Hyzon Motors has today revealed new test data from the latest generation of its proton exchange membrane (PEM) fuel cells which have been optimised for durability and longer operation life.
Recent tests conducted by certification services business TUV Rheinland showed that Hyzon’s new PEM fuel cells achieve volumetric power density exceeding 6kW/l, and gravimetric power density exceeding 5.5kW/l, according to a press release.
Although performance data was from short stack testing, it validates the potential of using full power fuel cells up to 500hp (370kW) for heavy mobility applications, therefore, reducing dependence on batteries
Craig Knight, CEO and Co-Founder of Hyzon Motors, said, “For nearly 20 years now, the Hyzon founding team have been fully focused on developing world class PEM fuel cell technology – the ‘engine’ of any hydrogen-powered vehicle – with the aim of producing the world’s most advanced fuel cell to accelerate the energy transition and decarbonise heavy commercial mobility.”
“With greater electrification of equipment and systems, there is a need for more powerful and lighter fuel cells to power heavy vehicles, machinery, trains and aircraft. This is where our PEM fuel cells will really excel; high power output and high-power density enable applications previously out of reach of fuel cell technology.”
