HYDROGEN PRODUCTION DEVICE AND HYDROGEN PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen production device which can effectively use the installation location.

SOLUTION: The hydrogen production device can be converted from a first form to a second form and includes at least one hydrogen production module. The hydrogen production module includes a photoelectric conversion part having a light-receiving surface and a back surface; and a first electrolysis electrode and a second electrolysis electrode provided on the back surface side of the photoelectric conversion part. The first and second electrolysis electrodes are provided so that an electrolyte solution is electrolyzed using the electromotive force produced when the photoelectric conversion part receives light to thereby generate a first gas and a second gas, respectively. The first form is a form in which generally the whole of the light-receiving surface included in the hydrogen production device can directly receive sunlight. The second form is a form in which the photoelectric conversion part included in the same or different hydrogen production module as described above is located on the light-receiving surface side or the back surface side of the photoelectric conversion part included in one of the hydrogen production modules as described above.
