Abstract
A metal seawater fuel cell includes a single cell or a battery pack which is composed of more than two single cells connected in series or in parallel or in series and parallel through circuits. The single cell has a metal anode arranged oppositely in a sealed single cell housing, a cathode carrying a hydrogen evolution catalyst, and a diaphragm arranged between the metal anode and the cathode, the bottom and the top of the single cell housing are respectively provided with fluid flow channels, and both ends of the fluid flow channels are respectively provided with openings communicated with the interior and exterior of the housing. The metal anode and/or single cell housing is placed in a closed transitional housing. The transitional housing is a degradable material or can be mechanically damaged by a driving device driven and started by a control device.
