Embodiment 1
[0019] A schematic flow chart of Example 1 of a fuel cell power generation system using liquid oxygen as an oxidant is shown in figure 1 Shown: This process is applicable to the proton exchange membrane fuel cell system of static drainage technology. This embodiment mainly considers the characteristics of the fuel cell static drainage technology, separates the thermal management of the fuel cell itself from the thermal management of the liquid oxygen system, and uses the heat exchanger to realize the excess of thermal energy.
[0020] combine figure 1 , the present invention is composed of a fuel cell module 1, a control valve 2, a buffer tank 3, a liquid oxygen storage tank 4, a circulating water pipeline 5, a circulating water pump 6, a monitoring unit 7, a heat exchanger 8, a water tank 9, a radiator 10, The hydrogen supply system 11 is composed.
[0021] The fuel cell module 1, the heat exchanger 8 and the radiator 10 constitute a thermal management circuit of the fuel c...
Embodiment 2
[0026] A schematic flow chart of Embodiment 2 of a fuel cell power generation system using liquid oxygen as an oxidant is shown in figure 2 Shown: This process is applicable to the proton exchange membrane fuel cell system with dynamic drainage technology. Considering the characteristics of the fuel cell dynamic water drainage technology, combining the thermal management waterway of the fuel cell itself with the thermal management waterway of the liquid oxygen system, the system will omit the heat exchanger 8 in Embodiment 1, and all the water circulation pipelines are at normal pressure Pipeline, the system is simpler. The specific implementation steps are as follows:
[0027] combine figure 2 , the present invention is composed of a fuel cell module 1, a control valve 2, a buffer tank 3, a liquid oxygen storage tank 4, a circulating water pipeline 5, a circulating water pump 6, a monitoring unit 7, a water tank 9, a radiator 10, and a hydrogen supply system 11. .
