| Outline of Final Research Achievements |
This study deals with water-absorbing porous electrolyte water electrolysis cell utilizing proton conduction on the surface of inorganic nanoparticles. The aim is to apply this cell for oxygen production in space. Electrolyte, gas-diffusion layer, electrodes are studied and electrolysis cell has been investigated.
By the combination of titanium-sulfate electrolyte, gas-diffusion layer consisting of carbon-PTFE composite, carbon-supported platinum cathode and iridium oxide anode, water electrolysis could operate without influence of gravity. Thus, the methodology for the operating of this water electrolysis cell was established.
