Abstract

The invention provides a piece of continuous hydrophobic treatment equipment for a gas diffusion layer of a fuel cell, which includes a transferring mechanism used for transferring a gas diffusion layer to be treated to an impregnating-draining-delivering mechanism, the impregnating-draining-delivering mechanism used for impregnating and draining the gas diffusion layer and transferring the gas diffusion layer to a drying mechanism, the drying mechanism used for drying the gas diffusion layer, and a collecting mechanism used for collecting the gas diffusion layer after drying. By adopting thetechnical scheme of the invention, the problem that the existing hydrophobic treatment equipment and method cannot realize continuous production is solved.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a device and method for continuous hydrophobic treatment of gas diffusion layers of fuel cells. Background technique [0002] Fuel cells have the advantages of low operating temperature, fast start-up, high specific power, simple structure, and convenient operation. Membrane electrode three-in-one assembly (MEA) is the core component of the proton exchange membrane fuel cell, and the gas diffusion layer is an important component of the membrane-electrode three-in-one assembly, which is an important channel for the transmission of reaction gas and generated water. In the preparation process of the membrane electrode, in order to improve the water management ability of the gas diffusion layer, the carbon paper that has been treated with hydrophobicity is usually used as the matrix of the gas diffusion layer, and the method of impregnating a hydrophobic agent solution, such as polytetraflu...
