CA HyPoTraDe: preparations for a liquid hydrogen fuel cell powertrain ground test (500kW) at NLR

In the frame of the clean aviation project HyPoTraDe, NLR in the Netherlands is preparing a new test facility for ground tests of liquid hydrogen-powered fuel cell powertrains. The presentation shows the preparation of the powertrain hardware involving two 100kW fuel cells, two large batteries, electrical power distribution and five propulsor units including the innovative use of a two-phase transfer loop for collecting fuel cell waste heat for the conditioning of liquid hydrogen.
