Effect of Dual-Flow Channel Structures on Electrochemical CO2 Reduction in Proton Exchange Membrane Electrolyzers
Autor: Youngseung Na, Min Gwan Ha, Hyun S. Park, Hee Young Park, Hyoung-Juhn Kim, Dirk Henkensmeier, Sung Jong Yoo, Jin Young Kim, So Young Lee, Jong Hyun Jang
Publikováno v: Frontiers in Energy Research, Vol 10 (2022)
Greenhouse gases such as carbon dioxide and methane are responsible for intensifying global warming. Consequently, a reduction in power plant outputs and an increase in capture and storage on-site are required to reduce greenhouse gas emissions. Rece
