Abstract

Perfluorosulfonic Acid (PFSA) film, commonly used in the Polymer Electrolyte Fuel Cells (PEFC), indicates conductance of proton and permeability of H₂O. In this study a mechanical composite mover device with this PFSA and hydrogen storage alloy (HSA) thin films was made up for expecting the movement driven by volume change in the course of hydrogen migration between PFSA and HSA layers. Hydrogen storage alloy, such as LaNi₅ indicates as much as 25% of volume change in the course of H₂ absorption in gas phase. Using this characteristics, a mechanical mover device was made of PFSA film of an electrolyte polymer sandwiched by hydrogen storage alloy thin films with Au-Pd intermediate layers. The mover device was operated by migrating hydrogen ions from the PFSA layer to the HSA layer, which were generated by electrolysis of H₂O in a PFSA layer. Electrical potential was given from the outsides lead wires. All experiments were carried out in the water. We confirmed large interesting movement generated by migration of hydrogen ion by applying electric potentials.
