Outline of Final Research Achievements

Proton implantation into phosphate glasses via an electrochemical reaction under hydrogen atmosphere was successfully confirmed using an originally developed in-situ FTIR equipment. Water molecules are indispensable for the proton implantation. We also confirmed a large creep displacement during the proton implantation by utilizing an originally developed electrochemical indenter. Results obtained here are significant for the application of phosphate glasses for a fuel cell electrolyte and preparation of an electrolyte/electrode assembly. We have also studied about the application of this simple electrochemical proton implantation technique for e.g. a new local modification/processing of glasses. We also confirmed for the first time about a proton emission of the implanted H+ by applying a high voltage for a sharpened proton conducting glass fiber.
