Boeing invented a new reversible fuel cell that generates energy as an engine and recharges itself off its own H20 byproduct. It will be used to power U.S. Navy microgrids and Department of Defense forward bases that need sustainable and redundant power systems in addition to what they have right now. Boeing's reversible fuel cell power plant technology may also have future applications for microgrid power for off-grid communities, disaster zone shelters, far-off research facilities in the Arctic and even in space missions.
