Problems solved by technology

Among them, the humidification methods with the least energy consumption are membrane humidification and tail gas circulation humidification. The disadvantage of membrane humidification is that the permeation of the membrane is very small, and humidification requires a large membrane area and number of sheets.
The amount of humidification is not easy to adjust arbitrarily, and when the reaction current is small, it is easy to cause excessive humidification, and liquid water is easy to block the flow field, causing single-chip reverse polarity
Humidification by bubbling method can control the water temperature of the humidifier to adjust, but it consumes a lot of energy, and there is liquid water at the outlet of the humidifier

Abstract

The invention discloses a fuel cell humidifier, which comprises a gas-liquid exchange area (2), a heat exchange area (3) arranged on the lower part of the gas-liquid exchange area (2) and a spray headcontrol area (5) arranged on the upper part of the gas-liquid exchange area (2), wherein the upper part of the gas-liquid exchange area (2) is provided with a gas inlet (1); the heat exchange area (3) is communicated with the lower part of a gas flow-out part (9); and the upper part of the gas flow-out part (9) is provided with a gas outlet (7). The fuel cell humidifier has the characteristics ofadjustable humidifier amount, no need of water storage tank, quick humidifying, capability of quickly achieving the set humidifying temperature and humidifying amount, and lower energy consumption.

Description

technical field [0001] The invention relates to a fuel cell humidifier. Background technique [0002] A fuel cell is a device that converts chemical energy into electrical energy through fuel combustion reactions in the battery. The negative electrode serves as the common interface between the fuel and the electrolyte, and also catalyzes the oxidation reaction of the fuel; while the positive electrode is the common interface between oxygen and the electrolyte. Catalyzes the reduction reaction of oxygen. Fuel cells are divided into phosphoric acid type (PAFC, phosphate fuel cell), molten carbonate type (MCFC, melt carbonate fuel cell), solid oxide type (SOFC, solidoxide fuel cell) and proton exchange membrane type (PEMFC, proton exchange membrane fuel cell). Among them, the proton exchange membrane fuel cell (PEMFC) can work in a low temperature environment. Because it uses a solid electrolyte, it can be applied to industries that require mobile energy, such as the automobi...
