| Title of the Research | Developing Porous Transport Electrode for Low Iridium Loading and High Current Density Operation of Polymer Electrolyte Membrane Water Electrolysis (PEMWE) |
| Outline of Research | Green hydrogen production by water electrolysis is a key technology for realizing a decarbonized society. The issue of high green hydrogen production cost is primarily due to operating expenditure and capital expenditure. PEMWE especially has clear advantage over other water electrolysis technologies due to its ability to operate at high current density. The overall electrode area could be reduced at high current density operation, leading to an overall reduction in capital expenditure. A significantly high amount of platinum group metal (PGM) catalyst used in the anode due to rate-determining anode reaction is also another issue. The objective of this research is to therefore develop a low PGM loading anode, while realizing high performance and high current density operation for overall reduction of capital expenditure. Currently, we have developed a novel anode, which has the potential to exhibit high catalytic activity and suppress mass transport resistance at high current density operation. |
