1. A mode selective electrode assembly, comprising
at least two electrodes having reactive polymeric layers on each side;
a proton exchange membrane;
a mode switching system,
wherein the mode switching system changes from an electrolysis cell mode to a fuel cell mode or from a fuel cell mode to an electrolysis cell mode by folding up the polymeric reactive layers of the electrodes.
 
3. A unitized regenerative fuel cell comprising, gas,
a mode selective electrode assembly,
at least two gas storage tanks with a pressure sensor for storing hydrogen gas and oxygen gas,
a water storage tank with a pressure sensor,
an external energy source, and
a power reservoir for storing energy,
wherein the mode selective electrode assembly, comprises of
at least two electrodes having reactive polymeric layers on each side;
a proton exchange membrane; and
a mode switching system, wherein the mode switching system changes from an electrolysis cell mode to a fuel cell mode or from a fuel cell mode to an electrolysis cell mode by folding up the polymeric reactive layers of the electrodes.
