Mg FC is resistant to disasters

Mg FC is resistant to disasters” in “Magnesium fuel cell, its anode made of flame-retardant Mg alloy” is written anew.

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 a disaster situation, if the pipeline for feeding city gas is damaged, the H2FC-contained CHP is inoperable even if the CHP itself is not damaged and is normally operable.
In this situation, the Mg FC is normally operable if the FC itself is not damaged and seawater (electrolytic solution) is available. The MgFC has a long life span (several tens years) as already described.
The MgFC may be used in the following way (see a photograph given below) in preparation for a disaster situation. A simple power supply system has an MgFC, a controller, a switch and others.
An output line of the power supply system is connected to a load, for example, TV, while a detecting line of the same for detecting an electric state of a power line in a house is coupled with the power line.
When a grid power supply stops in an emergency, the controller detects the power supply stop, instructs a related portion of the system to inject the electrolyte into the MgFC body, while at the same time operate the switch to connect the output line to the TV. The MgFC in turn operates to start power supply to the TV. TV is ceaselessly operating and presenting a TV program, for example, news.
In the test conducted at the end of April 2012, the MgFC could continuously power a 9-inch TV and 96 LEDs for 25 hours. See [PDF. pages 9 & 10]
