Tests of the Vehicle’s Powertrain with Hydrogen Fuel Cells at a Low Temperature

The article discusses issues related to the operation of fuel cells stack fed with hydrogen at low temperature. The test object was a Toyota Mirai passenger car, equipped with this type of powertrain. Tests were carried out in a thermoclimatic chamber at the Cracow University of Technology. They had an initial character, and their aim was to evaluate the work of individual subassemblies of the propulsion system, including the hydrogen supply system in terms of operational safety.
