A multifunctional fuel cell power supply device

Abstract

A multifunctional fuel cell power supply device, including a charging device and an inflating device, the charging device includes a box body, a fuel cell is placed in the box body, a first through hole is opened on the right side of the box body, and a charging interface is opened at the position corresponding to the first through hole of the fuel cell , there is a hydrogen interface device on the top surface of the box, a hydrogen bottle on the top surface of the box, and a limit device on the left side of the box. The hydrogen interface device includes a first sleeve, and the ninth through hole is opened on the first sleeve, and the ninth through hole There is an elastic telescopic rod inside, the right end of the hydrogen cylinder is a conical surface, a vertical rod is installed on the inner side of the hydrogen cylinder, an annular through hole is opened inside the hydrogen cylinder, and an annular box is arranged in the annular through hole, and the inflation device can effectively inflate the hydrogen cylinder. In the process of use, the invention only needs to manually toggle the elastic telescopic rod to open and close the hydrogen bottle, reducing the self-discharge phenomenon of the fuel cell, and when the hydrogen in the hydrogen bottle is used up, it only needs to be installed on the inflator The device can be used next time after being inflated, and the device can be reused.

Description

technical field [0001] The invention belongs to the field of fuel cell power supply equipment, in particular to a multifunctional fuel cell power supply equipment. Background technique [0002] Hydrogen fuel cell is the current global energy shortage and high oil price. It is urgent to find new energy as a substitute for fossil fuel.

[0002] Hydrogen fuel cell is the current global energy shortage and high oil price. It is urgent to find new energy as a substitute for fossil fuel. Fuel cell is considered to be the fourth generation power generation technology after hydropower, thermal power and atomic power generation. It converts oxidant through electrocatalytic reaction It is an efficient, safe, clean and flexible new power generation technology, and the proton exchange membrane fuel cell has high efficiency, high energy density, low reaction temperature, no noise, Due to its obvious advantages such as no pollution, it has broad application prospects in ground power stations, electric vehicles and portable power supplies. However, during the use of traditional hydrogen fuel cells, hydrogen cylinders are generally disposable and need to be Return to the factory to re-inflate, and during use, if the hydrogen cylinder is not removed, there will be self-discharge, which is not convenient to use
