Abstract

The invention belongs to the field of fuel cells and hydrogen production, provides a hydrogen production device, system and method for controlling the hydrogen production rate of a fuel cell, and solves the problems that the utilization rate of water in the system is reduced, the starting rate is slow, and the hydrogen production rate cannot be accurately controlled. According to the technical scheme, a water storage tank and a hydrogen production tank are connected in the mode that a pump or a pipe is filled with a wick, liquid water or steam slowly enters a system through an active matter filling tank hole, the good contact rate with active matter is kept in the process, and hydrogen is released; the surface of the water recovery tank is hollowed out to control the outflow rate of water and indirectly control the contact time with active substances; each space in the hydrogen production device can be filled with one or more water absorbing materials in advance, so that the stability of the reaction process rate is improved.

Description

technical field [0001] The invention belongs to the field of fuel cells and hydrogen production, and in particular relates to a hydrogen production device, system and method with a controllable hydrogen production rate for fuel cells. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Finding a safe, efficient and reliable hydrogen storage method to provide hydrogen for fuel cells is an important problem that needs to be solved urgently. [0004] At present, the commonly used hydrogen storage methods are physical hydrogen storage and chemical hydrogen storage. Physical hydrogen storage mainly compresses hydrogen, which is easy to release but unsafe at high pressure, and there are also problems such as low mass or volume hydrogen storage density and heavy mass of hydrogen storage tank; the difference is that chemical hydrogen storage can util...
