1. An apparatus for producing oxygen, comprising:
a reactor vessel,
a cathode electrode in the reactor vessel,
an anode electrode in the reactor vessel wherein said cathode electrode has a three-dimensional printed structure created by additive manufacturing with an ink formulation having polymer binders with catalytical precursors, wherein said ink formulation having polymer binders with catalytical precursors includes 0.5 g SbSO4, 0.258 g MnCl2, 3 g block copolymer binder pluronic F127, 3 g water and 1 g resorcinol-based prepolymer,
an electrolyte in the reactor vessel between said anode electrode and said cathode electrode,
a membrane in the reactor vessel between said anode electrode and said cathode electrode,
a power source for enhancing an electrical potential between said anode electrode and said cathode electrode, and
an oxygen outlet defining a passage from the reactor vessel for producing oxygen.
