Key Technology Development of Anion Exchange Membrane Electrolysis Hydrogen Production

Net-zero-emission has become a very important goal for the entire world in thenext 30 years, and H2 energy is one of the seven key technologies that canachieve net-zero carbon emissions in the future. Among all H2 energytechnologies, the green H2 production technology is one of the most importantissues presently. Among all kinds of the green hydrogen production technology,alkaline electrolysis (AEL), polymer electrolyte membrane electrolysis (PEMEL),anion exchange membrane electrolysis (AEMEL), and solid oxide electrolysis(SOEL) are currently the four main technologies based on water electrolysis. Theanion exchange membrane electrolysis has the both advantages of the protonexchange membrane electrolysis, which can produce hydrogen at high pressure,and the alkaline water electrolysis, which can use non-precious metal catalysts(such as Ni, Co, and Fe). Thus, AEMEL is considered a promising hydrogenproduction technology. As a result, this project focuses on the development of theelectrolyzer and its core components based on the anion exchange membraneelectrolysis.This three-year project is expected to develop a high-performance, low-cost, andhigh-efficiency hydrogen production electrolyzer based on alkaline ion exchangemembranes. In order to achieve this goal, this research will not only develop anelectrolysis stack, but also develop the key component, the membrane electrodeassembly for electrolysis. In addition, it is planned to develop an innovative ureawater solution electrolyzer to produce hydrogen in the third year. By developingthis new type of electrolysis technology, it is expected that the voltage ofelectrolysis can be reduced, and the energy storage efficiency with power-to-gascan be increased.This project has a great novelty and perspectiveness. It is expected to publishoutstanding academic papers and to achieve the development of a morecompetitive green H2 production technology at the end of the project. As a result,it is expected to raise the academic position and help Taiwan reach the goal ofnet-zero-emission in the future.
