Problems solved by technology

[0003] However, most of the existing metal fuel cells are disposable batteries, and the metal electrodes are plate-shaped. When the metal electrodes are consumed, the electric energy of the battery is released, and the battery can continue to discharge only after the metal electrodes are renewed.
The operation of replacing the metal electrodes is very cumbersome, and the unreacted residual metal plates also cause waste, increasing the cost of the battery

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a metal fuel cell and its fuel cell system. Background technique [0002] Due to its high specific energy, metal fuel cells have become the research and development direction of a new generation of power batteries. [0003] However, most of the existing metal fuel cells are disposable batteries, and the metal electrodes are plate-shaped. When the metal electrodes are consumed, the electric energy of the battery is released, and the battery can continue to discharge only after the metal electrodes are renewed. The operation of replacing the metal electrodes is very cumbersome, and the unreacted residual metal plates also cause waste, increasing the cost of the battery. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a metal fuel cell and its fuel cell system, so as to ac...
