Title
(EN) GAS PRODUCTION APPARATUS
(JA) ガス製造装置
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a gas production apparatus capable of maintaining a high gas generation efficiency regardless of the passage of time and of stably manufacturing hydrogen and oxygen gases as perfectly separated high-purity gases.

SOLUTION: The problem-solving gas production apparatus includes: a module consisting of multiple serially connected PN junctions each possessing a light reception surface and constituted by an inorganic semiconductor; two gas generation units configured respectively on open ends of the PN junctions at both ends of the module on the side of the light reception surface; an aqueous electrolyte solution contacted with the two gas generation units; an electrolytic chamber for storing the gas generated on each gas generation surface; and an ion-permeable, gas-impermeable diaphragm for partitioning the electrolytic chamber into two regions each including one gas generation unit so as to store either of hydrogen and oxygen.
