FUEL CELL SYSTEM FOR INDUSTRIAL ELECTRIC VEHICLE

摘要

A fuel cell system for a forklift includes a fuel cell stack consisting of an anode, a cathode and a coolant passage. A fuel tank is provided for supplying hydrogen to the anode. An air blower is provided for supplying air to the cathode. A pump is used for circulating coolant through the coolant passage. A heat exchanger is positioned at downstream of the fuel tank and the pump and in fluid coupling therewith. The hydrogen absorbs heat from the coolant in the heat exchanger before the hydrogen flows to the anode. The air absorbs heat from the coolant in a radiator before the air flows to the cathode. The radiator is in fluid coupling with the heat exchanger and the coolant passage and located therebetween.

1. A fuel cell system for an industrial electric vehicle comprising:
a fuel cell stack having an anode, a cathode and a coolant passage; a fuel tank; a heat exchanger having a first fluid flow-through passage and a second fluid flow-through passage so as to allow transfer of heat from the first fluid to the second fluid, the first fluid flow-through passage being in fluid communication with the fuel tank and the fuel cell stack anode; an air blower for drawing air into the fuel cell stack cathode; and a pump in fluid communication with the second fluid flow-through passage of the heat exchanger and the fuel cell stack coolant passage; wherein, the pump drives coolant to flow into the fuel cell stack coolant passage and through the second fluid flow-through passage of the heat exchanger, and fuel flows from the fuel tank through the first fluid flow-through passage of heat exchanger absorbing heat from the coolant before flowing to the fuel cell stack anode.
