Auxiliary electric pile simulation device for fuel cell power generation system testing

Abstract

The invention relates to an auxiliary electric pile simulation device for fuel cell power generation system testing. The auxiliary electric pile simulation device comprises a cathode simulation module, an anode simulation module and a cooling simulation module. The cooling simulation module comprises a cooling water inlet, a cooling water pipeline and a cooling water outlet which are sequentiallyconnected. A first heater and a first regulating valve are arranged on the cooling water pipeline. The anode simulation module comprises an anode gas inlet, an anode gas pipeline, an exhaust port andan anode gas outlet. The anode gas pipeline is a three-way pipe, wherein one end is connected with the anode gas inlet, and the other two ends are respectively connected with the exhaust port and theanode gas outlet. Compared with the devices in the prior art, the physical state change of the electric pile in the power generation process can be simulated instead of the electric pile and the fuelconsumption simulation, and the electric pile flow resistance simulation and the gas humidity simulation in the electric pile can be realized so that the system testing is accurate and reliable, and meets the actual working state.

Description

technical field [0001] The invention relates to the field of fuel cell testing, in particular to an auxiliary stack simulation device for testing a fuel cell power generation system. Background technique [0002] The fuel cell power generation system is mainly composed of a stack, a hydrogen supply subsystem, an air supply subsystem, a heat management subsystem and a controller. The cooperative work of each subsystem and the precise control of each parameter can ensure the high output performance of the fuel cell. For the test of the existing fuel cell power generation system in the research and development stage, two methods are generally adopted: one is to test and verify the overall comprehensive performance after integrating each subsystem; the other is to test the components of the subsystem in a separate subsystem platform. Individually tested for verification. However, there are the following problems in these two conventional test methods: 1. In the process of testi...

Problems solved by technology

However, there are the following problems in these two conventional test methods: 1. In the process of testing the integrated system, if there are design defects in the subsystem, the direct use of the stack module may cause irreversible damage to the stack

2. If the existing simple analog stack is used, it can only realize the design of a separate subsystem for verification. For example, during the test of the fuel supply subsystem, the physical state parameters of the stack in the subsystem can be individually simulated by using the stack simulation device , but it is impossible to fully and accurately simulate the physical state of the integrated fuel cell engine system, such as simultaneously simulating the consumption of fuel and oxidant, the generation of water in the stack, the generation of wet gas on the cathode side, and the heat generation of the stack, etc. There is a certain deviation in the test results
