Abstract

The invention provides an intrusive hybrid air-cooled fuel cell alternating current power supply which comprises a fuel cell stack, an alternating current voltage stabilization module and a direct current voltage stabilization module which are used for stabilizing voltage, a control circuit board and an outer structure part (comprising an outer frame and a skin), and is a power supply module with independent functions and a complete structure, and only a commercially available hydrogen source needs to be provided for the power supply module. The power supply can be used as an emergency power supply to supply power to electric appliances in the field, in suburbs or in remote areas. According to the invention, the overall output power of the system can be improved by adjusting the number and overall dimensions of the single cells of the cell stack of the fuel cell, the system can be conveniently used as a portable application to provide 220V mains supply, the problems of high noise and unfriendliness to the environment during power supply of a gasoline engine are solved, and the system has the advantage of environmental protection. With the improvement of the capacity and the output capacity of the auxiliary battery, the working time and the multiplying power output capacity of the auxiliary battery are multiplied, and the auxiliary battery has the characteristics of modularization and miniaturization.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, in particular to an intervening hybrid air-cooled fuel cell AC power supply. Background technique [0002] Hydrogen fuel cell (PEMFC for short) is a device that continuously converts the chemical energy of fuel (and oxidant) into electrical energy. The chemical energy in the fuel and oxidant is directly converted into electrical energy and water. It has the advantages of high power density, high energy conversion efficiency, and environmental friendliness. It has been demonstrated and promoted in a certain range of military and civilian fields in China. According to the different cooling medium, it is divided into air-cooled fuel cell system and water-cooled fuel cell system. At present, due to its simple structure and small size, the air-cooled fuel cell system has received increasingly close attention in military and civilian applications such as portable power supplies and mobile power sta...
