Fuel Cell

The Fuel Cell is a power source of the Habitat, connected to the secondary Habitat power bus, using the same fuel as the main Reactor, though far less efficiently. However, unlike the Reactor, the fuel cell works cold. Therefore the fuel cell is used when the main reactor is off, broken, or malfunctioning, as while Cold Starting the main Reactor. Since, during flight, the Reactor, not the fuel cell, provides power, it is not fatal to blow a fuel cell after launch, and the AYSE drive can automatically repair or replace a blown cell.
