Title:
HYDROGEN GENERATOR
Document Type and Number:
WIPO Patent Application WO/2024/005270
Kind Code:
A1
Abstract:
This hydrogen generator includes a first region and a second region separated by a semi-permeable membrane, a first electrode provided in the first region, a second electrode electrically connected to the first electrode and provided in the second region, a depolymerization unit separated from the second region, and an electron transfer medium provided in the first region and the depolymerization unit. The electron transfer medium is simultaneously reduced while decomposing lignocellulose in the depolymerization unit, and oxidized at the first electrode in the first region, and protons are reduced at the second electrode by electrons generated from the oxidation.
