Abstract: An apparatus and method for producing hydrogen is disclosed. A housing includes a conversion compartment fluidly connected to a gas collection compartment. A filter is disposed between the conversion compartment and the gas collection compartment. The filter is permeable to select molecules, such as hydrogen and oxygen. An energizer module is adapted to generate an oscillating signal. A piezo electric ceramic element is disposed within the conversion compartment and is electronically coupled to the energizer module to receive the oscillating signal. The piezo electric ceramic element preferably comprises a substrate and a piezo electric ceramic membrane affixed to the substrate.
