Hydrogen storing unit and coupled fuel cell

Abstract

The invention discloses a hydrogen storing unit for a coupled fuel cell, comprising a hydrogen storing container, at least one gas inducting channel and hydrogen storing materials. The hydrogen storing container is internally provided with at least two hydrogen storing cavities which are sealed from the outside and are parallel to each other. The gas inducting channel is formed in the hydrogen storing container and penetrates through the at least two hydrogen storing cavities, and hydrogen can enter or flow out of the hydrogen storing cavities through the gas inducting channel. The hydrogen storing materials are filled in the hydrogen storing cavities. According to the hydrogen storing unit, the hydrogen storing cavities are mutually parallel and have smaller diameters, which is beneficial to the uniform distribution of the temperature of the inner hydrogen storing materials and can better prevent the hydrogen storing materials from being powdered, thereby the service life of the hydrogen storing materials is prolonged. In addition, the hydrogen storing unit can be well coupled with a fuel cell monomer in structure, thereby realizing effective thermal management of the hydrogen storing unit and the fuel cell. The invention also discloses the coupled fuel cell provided with the hydrogen storing unit.

Description

technical field [0001] The invention relates to the field of hydrogen energy, in particular to a coupled hydrogen fuel cell and a hydrogen storage unit used therein. Background technique [0002] A fuel cell is a continuous power generation device that converts chemical energy in externally supplied fuel and oxidant into electrical energy. Due to high power density and energy density, clean and efficient, and wide power range, fuel cells have broad application prospects in various fields such as micro power sources, mobile power sources, vehicle engines, and fixed power stations. [0003] At present, proton exchange membrane fuel cells that are close to practicality mainly use hydrogen as fuel, and mainly use three hydrogen storage methods: high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage, and metal hydride solid-state hydrogen storage. These three hydrogen storage methods are currently used in fuel cell vehicles. Among them, the high-pressur...
