A magnesium fuel cell (Mg FC) has been developed additionally.
The Mg FC specifications are: electric capacitor = 60 Ah, and size = 26cm×17cm×10cm. In structure, a negative electrode (active material) = incombustible magnesium, a positive electrode (active material) = oxygen gas, and electrolytic solution = saline solution. The prototype successfully charged 120 mobile phones at 360 W as its output. In use, the saline solution is set to the FC body.
The FC body is normally operable at its rated output power even after it is left for several tens years in a state that the solution not set to the FC body.
The Mg FC is resistant to disasters.
In the case of the hydrogen-based fuel cells currently used, for example, the residential CHP (ENEFARM) reforms city gas to produce hydrogen and uses the produced hydrogen for its fuel. In disaster situation, if the pipe- line feeding city gas is damaged, it is substantially impossible to operate the CHP even in case where the CHP itself is not damaged and could normally operate. On the other hand, the Mg FC is normally operable if the electrolytic solution is available, with its long durability of several tens years.
lytic solution is available and since the durability of the FC is very long, several tens years.
