| Outline of Final Research Achievements |
Fast hydrogen energy conversion systems were developed in combination with solid state ionics and chemical-looping technology. For chemical energy conversion cycles: (1) reduction reaction (i.e., chemical energy storage) (2) hydrogen production (3) total oxidation (heat recovery and regeneration of oxygen carriers), we developed a thermochemical-looping system and an electrochemical-looping system. Composite oxygen carriers consisting of an oxide ion electron mixed conductor and a metal oxide were synthesized successfully. Thus we obtained oxygen carriers with good performance on reduction reaction in hydrogen and reoxidation in steam. In addition, we developed a novel proton-conducting fuel cell for an electrochemical-looping system, and examined the feasibility of the proposed system.
