Abstract

The invention provides a device for testing fuel cell stacks, which comprises a working gas supply system connected with a fuel cell, and a control system. The working gas supply system comprises a hydrogen pipe and an air pipe; wherein a first flow control unit for detecting and controlling the flow of hydrogen is arranged on the hydrogen pipe; a second flow control unit for detecting and controlling the flow of air is arranged on the air pipe; and the control system is electrically connected with the first flow control unit and the second flow control unit respectively, and is used for collecting detecting signals sent by the first flow control unit and the second flow control unit so as to record the hydrogen flow in the hydrogen pipe and the air glow in the air pipe. the device has the advantages of effectively solves the problem that the correlation data of hydrogen and air flow and fuel cell performance parameters under the loading condition of fuel cell stacks cannot be detected in the prior art.

Description

technical field [0001] The invention relates to the application field of fuel cell technology, in particular to a device for testing a fuel cell stack. Background technique [0002] A fuel cell is an environmentally friendly, efficient, and continuously working power generation device. Taking the proton exchange membrane fuel cell (PEMFC) as an example, the fuel gas enters from the anode side, the hydrogen atoms lose electrons at the anode and become protons, the protons pass through the proton exchange membrane to the cathode, and the electrons reach the cathode through an external circuit at the same time. Electrons combine with oxygen to form water. Fuel cells convert chemical energy into electrical energy in a non-combustion manner, and are not limited by the Carnot cycle, and the direct power generation efficiency is as high as 45%. The fuel cell system takes the battery stack as the core power generation device, integrates power management, thermal management and oth...
