A system includes a microstructure layer, a photovoltaic layer disposed over the microstructure layer comprising a positive P-type layer and a negative N-type layer, a hydrogen collection micro-chamber formed through the microstructure layer and the negative layer, and an oxygen collection micro-chamber formed through the microstructure layer and the photovoltaic layer. A cathode may be disposed within the hydrogen collection micro-chamber and an anode may be disposed within the oxygen collection micro-chamber. The micro-chambers may be spaced between about 1 and 10 micrometers apart. An insulating layer may be disposed between the microstructure layer and the photovoltaic layer. A supplemental storage layer may be disposed over the photovoltaic layer such that a storage portion is in alignment with the hydrogen collection micro-chamber. MEMS actuators may be located at the ends of the hydrogen collection micro-chamber to facilitate hydrogen storage and release.
