Abstract

The invention provides a fuel cell power system which comprises a main fuel cell stack, a control device, a first reaction gas supply device used for providing reaction gas for the main fuel cell stack, a second reaction gas supply device and an oxidant supply device used for providing oxidants for the main fuel cell stack, wherein a first gas inlet communicated with the first reaction gas supply device is formed in the main fuel cell stack; the first reaction gas supply device is electrically connected with the control device; the second reaction gas supply device and the first reaction gas supply device are independent of each other; the second reaction gas supply device is electrically connected with the control device; the first gas outlet of the second reaction gas supply device is communicated with the first gas inlet of the main fuel cell stack. According to the fuel cell power system, the problem of relatively low starting speed of a fuel cell system in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell power system. Background technique [0002] In the existing technology, such as figure 1 As shown, the fuel cell power system includes a first reactant gas supply device 1', an oxidant supply device 8', a fuel cell stack 2', a power conversion device 7', a drive motor and a control module. Taking the transportation field as an example, the fuel cell power system can be used as a power source for fuel cell vehicles. The fuel is high-pressure reaction gas, the oxidant is air, and pure water is generated. It is one of the main development directions for energy saving, emission reduction, and green energy. [0003] However, the above-mentioned first reactant gas supply device 1' of the fuel cell power system is generally a high-pressure gas cylinder for hydrogen storage. Since the pressure of the reactant gas tank should not be too high, the energy density is far infe...
