The battery is fitted with a cooling circuit (2) having a circulation pump (10) and a heat exchanger (40). The cooling circuit includes a heater (14) controlled by a temperature sensor (17) which switches on the heater when the temperature is close to the cooling circuits distilled water freezing temperature. The heater includes an electrical resistance (15) mounted in the cooling circuit, the supply to it is from batteries (16), electrical network and fuel cell itself. n an alternative version the heating resistance is also fed from the electro-chemical battery (fuel cell), which has an auxiliary circuit , fed with hydrogen and air, tapped from the principal supply circuit so as to operate the battery (1) at a lower power than normal operating power. The auxiliary circuit has a calibrated passage designed to supply sufficient hydrogen to generate the current necessary to supply the heating resistance. A fan (20) is included in the air part of the auxiliary circuit. |
