Abstract: A hybrid electrical power system for an industrial electric vehicle such as an electric forklift, includes a base weight, an electrical power module on the base weight and front and rear frame supports erected from the base weight and sandwiching the electrical power module therebetween. The electrical power module includes a fuel cell module having a fuel cell stack, a hydrogen storage tank and an air blower, and a Li-ion rechargeable battery module. A weight of the base weight is about 70%-80% of a total weight of the system. A weight of a fixer for the hydrogen storage tank is about 10% of the total weight of the system. The blower is connected to a filter via a resonator to reduce a noise level generated by air blower. Electrode plates and membranes of the fuel cell stack are vertically stacked up.
