ENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 1, January 2025.The design principles for m‐PBI membranes to be used in a vanadium redox flow battery are formulated through the synthesis and analysis of N‐alkylated and N‐benzylated m‐PBI derivatives. The correlation between molecular architecture and electrolyte affinity, ionic conductivity, and cell performance is described, with N‐alkylated membranes displaying ...

Performance evaluation of PEFC stack
, 1996 Polymer electrolyte fuel cells (PEFCs) have many advantages such as high current density, short start-up time and endurance for start-stop cycles. Making use of these advantages, Fuji Electric has been working with the Kansai Electric Power Co., Inc. to explore practical applications of PEFCs for an electric utility use.
