Problems solved by technology

But it also has many disadvantages: (1) The pipeline design of the humidification mechanism and the connection with the battery are quite complicated (2) The humidification amount is not easy to control and adjust (3) When the load is large, the gas humidification is often difficult to reach saturation (4) It is not easy Carry out repair and maintenance work
[0005] Patents related to the humidification design of reaction gases in fuel cell systems have also been proposed and improved in recent years. The previous cases, such as U.S. Patent No. 5,482,680 and No. 5,527,363, mainly add a fuel cell stack (Cell Stack) The disadvantage of the humidification section is that the volume and weight of the battery stack are greatly increased. In addition, the design of the fuel, oxidant and water flow channels inside the battery stack is quite complicated.

Embodiment Construction

[0032] According to the external gas humidifying device of the fuel cell disclosed in the present invention, please refer to Fig. 1, it is applied to the humidification of the reaction gas of the fuel cell (not shown in the figure), and the reaction gas can be hydrogen (H2) or air (air) Heating and humidification of gas. The main components of a fuel cell include a proton exchange membrane (PEM for short), a catalyst layer (Catalyst Layer), a gas diffusion layer (GDL for short), and a bipolar plate (Bipolar Plate). When the PEMFC battery is in operation, the oxidation reaction of hydrogen (H2) is carried out at the anode (Anode), and the oxidation reaction of oxygen (O2) is carried out at the cathode (Cathode). 2 ) reduction reaction. First, the reaction gas is catalyzed by the catalyst to decompose hydrogen (H2) into hydrogen ions (H + ) and electrons (e - )(H 2 →2H + +2e - ), electron (e - ) flows from the anode to the external circuit of the battery, and flows into t...

Abstract

The invention is an external gas humidifier for fuel battery, recycling high temperature waste heat produced by fuel battery and recovering the waste heat to reacting gas (H2 or air) and then processing by gas humidifier, able to effectively raise gas humidity in a short time, when the humidified gas enters into the fuel battery, it can make high molecular film obtain good humidifying effect so as to improve power generating efficiency and service life of the fuel battery.

Description

technical field [0001] The invention relates to a gas humidifying device, which is applied to a proton exchange membrane fuel cell, in particular to a kind of recycling and utilization of high-temperature waste heat generated by the fuel cell, and then through the treatment by the gas humidifying device, the reaction gas can be processed in a short time. Humidification of the external air of a fuel cell to increase its moisture content. Background technique [0002] Proton Exchange Membrane Fuel Cells (PEMFCs) are a kind of hydrogen (H 2 ) and oxygen (O 2 ) The device for generating electricity has become a technology developed and promoted successively by countries all over the world due to its low operating temperature, fast start-up, high energy density, low pollution, and wide range of applications. [0003] The main components of a typical proton exchange membrane fuel cell (PEMFC) include a proton exchange membrane (Proton Exchange Membrane, referred to as PEM), a ca...
