FY 1985 report on research and development project commissioned by the Sunshine Project. Research and development of electrolysis of water by combined thermochemical, photochemical and electrochemical cycles; 1985 nendo netsu kagaku, hikari kagaku, denki kagaku konsei cycle ni yoru mizu bunkai no kenkyu kaihatsu seika hokokusho

Abstract

Reported herein are the FY 1985 research results on the combined water electrolysis cycles by effective utilization of sunlight. The tests for determining activity coefficient of an iron/iodine system is continued from the previous year, and the results are used to find the optimum conditions under which the photochemical and electrolysis reactions are effected simultaneously in a light-irradiated electrolysis tank. It is found that a photochemical reaction efficiency of approximately 0.3% is obtained at 5 W/cm{sup 2} as light intensity and 25 degrees C. For electrolysis of water by the multi-stage hybrid cycles, it is necessary for the reaction in each stage to proceed to almost the same extent so that it gives a just enough quantity of product for the subsequent stage. The data obtained are analyzed comprehensively, while taking the system matching conditions into consideration. The system for simultaneously measure two or more parameters, developed in the previous year, is equipped with a high-level language compiler of high effective speed, to simultaneously measure these parameters at shorter intervals.
