Salinity gradient power driven water electrolysis for hydrogen production

Popis výsledku v původním jazyce

The present work demonstrates an innovative system combining Reverse Electrodialysis (RED) and Alkaline Polymer Electrolyte Water Electrolysis (APEWE) for sustainable hydrogen production. The Salinity Gradient Power (SGP)-RED unit was tested with a thermally regenerative solution of NH4HCO3 in the concentration range of 0.15-1.5 M, whereas the water electrolysis unit equipped with quaternary ammonium functionalized anion selective membrane, Ni anode modified with Platinum Group Metal (PGM)-free electrocatalyst, Ni cathode modified with an electrochemically Reduced Graphene Oxide (RGO) was investigated at a varying temperature (50 - 80 °C). The integrated RED-APEWE system reached a maximum hydrogen production rate of 3.0x10-3 mol H2/h per cm2 of electrode surface area. Owing to the use of the thermally regenerative NH4HCO3 solution, this work presents a profound basis to design a system allowing the conversion of lowgrade waste heat into electricity in a closed loop with simultaneous production of hydrogen using salinity gradient energy.
