Hydrogen production by biomass product depolarized water electrolysis
Patent
·
OSTI ID:5525988
A process is disclosed for hydrogen production by water electrolysis and a process of depolarizing the anode of a water electrolysis cell by oxidizing a biomass product which may be monosaccharides, lignins, and mixtures thereof. The process of this invention avoids molecular oxygen evolution and results in high purity hydrogen at cell potentials substantially less than required for normal water electrolysis involving oxygen evolution. The process utilizes biomass products which are readily available and cost effective. High consumption of biomass product is achieved with an anode of lead-rich ruthenium polychlore compounds.
