Abstract
An arrangement for a vehicle includes a fuel cell, an electric traction and/or propulsion motor, and a single cooling circuit cooling the fuel cell and the electric motor. The cooling circuit includes two parts: a first, high-flowrate and high-temperature part including a high-temperature exchanger and a second, low-flowrate and low-temperature part including a low-temperature exchanger. The first part cools the fuel cell and the second part cools the electric motor. The first part includes a high-flowrate pump, in particular for a high flowrate of between 8000 l/h and 9000 l/h and the second part includes a low-flowrate pump, in particular for a low flowrate of between 2000 l/h and 3000 l/h.
