Tests of the vehicle's power unit with fuel cells at a reduced ambient temperature

The article presents the results of preliminary tests of the vehicles powertrain with fuel cells, carried out in a thermoclimatic chamber in a reduced temperature box. The aim of this research is to facilitate the introduction of this type of vehicle to the market and guarantee correct operation in changing climatic conditions. In tests, the use of a new type of vehicle drive system and the use of hydrogen as a commonly available fuel is of great importance.
