Title:
WATER ELECTROLYSIS APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/036128
Kind Code:
A1
Abstract:
Control of the aperture of an oxygen pressure control valve (21) comprises: a first feedback control for controlling, on the basis of the internal tank pressure detected by a first internal tank pressure-detecting unit (22), the aperture of the oxygen pressure control valve (21) so that the difference between the internal tank pressure and a predetermined target pressure is reduced; and a first feedforward control for controlling the aperture of the oxygen pressure control valve (21) on the basis of the electric current detected by an electric current-detecting unit (15). Control of the aperture of a hydrogen pressure control valve (26) comprises: a second feedback control for controlling, on the basis of the internal tank pressure detected by a second internal tank pressure-detecting unit (27), the aperture of the hydrogen pressure control valve (26) so that the difference between the internal tank pressure and the target pressure is reduced; and a second feedforward control for controlling the aperture of the hydrogen pressure control valve (26) on the basis of the electric current detected by th electric current-detecting unit (15).
