The photoanode and the cathode are each positioned IN withinthe solar housing and electrically coupled to the external power generation circuit. The electrolyte membrane is positioned 1-1 C between and electrochemically engaged with the photoanode and the cathode forming a photocatalytic cell. The solar housing com - el prises a closed-loop water chamber having an anode side flow channel, a cathode side flow channel, a recombined water channel, 0and an oxygen diffusion membrane. Further, the oxygen diffusion membrane is positioned and configured to inhibit recombined wa- ter generated at the cathode from flowing from the cathode side to the anode side along the oxygen transport channel and permit re - .,. combined water generated at the cathode from flowing from the cathode side to the anode side along the recombined water channel.
