Abstract

The invention relates to a fuel cell humidifier and a fuel cell. The fuel cell humidifier comprises a plurality of flow deflectors and humidifying membrane units arranged in the middle parts of the flow deflectors, wherein, the humidifying membrane units cover the adjacent flow deflectors, and the humidifying membrane unit comprises a humidifying membrane and two carbon fabrics where the humidifying membrane is clamped therebetween. The fuel cell comprises the fuel cell humidifier. The fuel cell humidifier and the fuel cell provided by the invention have the advantages that the proton exchange membrane is not easy to become deformed and is convenient for arrangement.

Description

technical field [0001] The invention belongs to the field of fuel cells, in particular to a fuel cell humidifier and a fuel cell. Background technique [0002] A proton exchange membrane fuel cell consists of a membrane electrode assembly (Membrane Electrode Assembly; hereinafter referred to as: MEA) and gas deflectors attached to both sides of the MEA to form a basic unit. When a certain pressure of hydrogen and oxygen (or air) is added to the gas deflectors on both sides of the MEA, electricity will be generated due to electrochemical reactions. In specific applications, the added gas must be moist. Wet gas can improve the power generation efficiency of the proton exchange membrane fuel cell, while dry gas will also take away the water on the surface of the MEA, which is easy to cause MEA failure. Drying produces cracks and damage. In hydrogen-oxygen fuel cells, dry oxygen is also prone to spontaneous combustion. If the gas humidification treatment is not good, it will ...
