Embodiment Construction

[0013] See figure 1 , the present application provides a fuel cell stack test bench 10 and a method for using the same. The fuel cell stack test bench 10 includes a hydrogen system 100 and an air system 200 . The hydrogen system 100 includes a hydrogen circulation pump 101 , a tail valve 103 and an anode back pressure valve 102 . The air system 200 includes an air circulation pump 201 and a back pressure valve 202 . The hydrogen circulation pump 101 is used to circulate hydrogen between the hydrogen inlet of the fuel cell stack 500 and the hydrogen outlet of the fuel cell stack 500 . The exhaust valve 103 and the anode back pressure valve 102 are arranged at the hydrogen outlet of the fuel cell stack 500 to discharge the hydrogen tail gas. The air circulation pump 201 is used to circulate air between the air inlet of the fuel cell stack 500 and the air outlet of the fuel cell stack 500 . The cathode back pressure valve 202 is arranged at the air outlet of the fuel cell sta...

Abstract

The invention provides a fuel cell pile test bench, which comprises a hydrogen gas system and an air system. The hydrogen gas system comprises a hydrogen gas circulation pump, a tail exhaust valve andan anode back-pressure valve. The air system comprises an air circulation pump and a cathode back-pressure valve. An accessory configuration mode for simulating different fuel cell engine systems isrealized by controlling whether accessories contained in the hydrogen gas system and the air system operate or not assisted by a computer. In addition, for the same accessory configuration mode, devices in the hydrogen gas system and the air system are modularly arranged, are convenient in disassembly and assembly, and are easily replaced with components of different models in the same series. Thefuel cell pile test bench and the using method thereof solve the problems of low test efficiency and high cost in the process of simulating different accessory configuration modes of the pile.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a fuel cell stack test bench and a method for using the same. Background technique [0002] Proton exchange membrane hydrogen fuel cell is an energy conversion device that directly converts chemical energy into electrical energy by electrochemical reaction. Its clean and efficient energy conversion features make it gradually applied in the field of vehicles. [0003] The proton exchange membrane hydrogen fuel cell used in the vehicle field needs to integrate the fuel cell stack with the peripheral hydrogen system, air system and cooling system, and to be electrically connected to loads such as vehicle assembly and electric drive system. The hydrogen system is mainly responsible for providing hydrogen supply to the stack, and the pressure and flow of hydrogen entering the stack need to be adjusted according to the operating conditions; the air system is to provide an appropriate amount o...
