Original Abstract Submitted
a testing apparatus and testing system for a fuel cell stack is disclosed. the testing apparatus includes a gas supply control module and a backpressure control module, both of which are detachably disposed within the main body. the gas supply control module incudes: a mass flow controller for controlling the flow rate of dry gas; a mixing tube, coupled to the mass flow controller and adapted to receive steam and dry gas, wherein the dry gas and steam are mixed in the mixing tube to form humidified gas; and a first gas heat exchanger, coupled to the mixing tube and adapted to be coupled to the fuel cell stack, wherein the first gas heat exchanger is configured to provide temperature-regulated humidified gas to the fuel cell stack. the backpressure control module is adapted to be coupled to the fuel cell stack and is configured to regulate the pressure of the exhaust gas from the fuel cell stack. in this manner, the modular design allows for the centralized arrangement of relevant components, bringing the total volume of the gas chamber in the gas supply circuit closer to the total volume of the gas chamber at the vehicle level, thereby improving testing performance.
