Abstract

The invention belongs to the technical field of fuel cell detection, and relates to a flow field optimization verification device and method. A sensor is embedded in a detection plate. The detection plate and a flow field plate are bonded together to assemble a detection composite plate, and the detection composite plate is arranged in a fuel cell stack to realize on-line detection of the temperature, humidity or pressure at any position inside a fuel cell. The flush-mounted installation has no effect on a membrane electrode and a reaction gas flow channel. The sensor and the flow channel arearranged in the detection plate and the flow field plate respectively, and the detection plate and the flow field plate are closely connected. The structure is convenient for disassembly and assembly.The detection plate can be assembled with and match flow field plates with different flow channels to form different detection composite plates to achieve on-line detection of a bipolar plate. Therefore, the same detection plate can be used to carry out optimization verification on bipolar plates with different flow fields. The device has the advantages of good practicality, versatility and reliability and low manufacturing cost. One plate is multipurpose, which saves the optimization and verification costs of bipolar plates.

Description

Technical field [0001] The invention belongs to the technical field of fuel cell detection, and more specifically, relates to a flow field optimization verification device and method. Background technique [0002] Traditional fossil energy reserves are limited, and the consumption of fossil energy also brings a series of environmental problems. Therefore, it is undoubtedly a hot spot to find a new clean and efficient energy utilization method. A fuel cell is an electrochemical cell whose main principle is to directly convert the chemical energy in the fuel and oxidant into electrical energy through a redox reaction. As an important branch of the fuel cell field, the proton exchange membrane fuel cell (PEMFC) not only has the general characteristics of fuel cell such as high energy conversion efficiency and environmental friendliness, but also has fast startup speed at room temperature, small size, and no electrolyte loss. , Easy to drain, long life, high specific power and speci...
