Abstract

The invention belongs to the field of fuel cells, and discloses a visualized fuel cell device. The visualized fuel cell device comprises a cathode flow field unit, the cathode flow field unit is conductive; an MEA membrane electrode, wherein the upper surface of the MEA is laminated with the bottom surface of the cathode flow field unit; and an anode flow field unit, wherein the top surface of theanode flow field unit is laminated with the lower surface of the MEA, the anode flow field unit is conductive, at least one of the anode flow field unit and the cathode flow field unit is transparent, and the top surface of the anode flow field unit and the bottom surface o the cathode flow field unit are respectively provided with grooves to form a flow path and form a ridge. The flow path is atransparent flow path by arranging at least one of the anode flow field unit and the cathode flow field unit to be transparent, a high-speed camera equipped with a microscope head is adopted to alignwith an area to be shot to achieve the visualization of the top portion or the bottom portion and the side of the flow path and achieve the visualization of the flow state and the distribution of twophase flows in the fuel cell.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, in particular to a visualized fuel cell device. Background technique [0002] Proton exchange membrane fuel cells have the advantages of low operating temperature, high efficiency, and environmental protection, and are an important part of the future vehicle power system. However, due to the water management problem of proton exchange membrane fuel cells, further improvement of its durability and performance is restricted. Especially under high current density conditions, a large amount of water, the product of the electrochemical reaction, will be produced. If the water cannot be discharged quickly at this time, it will block the flow channel and the pores of the diffusion layer, causing the reaction gas to fail to reach the reaction interface to react and flow channel Increased resistance and other issues. [0003] The fuel cell visualization device is a low-cost, intuitive observation dev...
