Abstract Herein, we study the preparation and characterization of a new kind of proton exchange membrane. In the proton‐conducting membrane of poly(vinylidene fluoride) (PVDF)/poly(ethylene oxide) (PEO)/dodecyl benzenesulfonic acid (DBS‐H), we use PEO as “proton solvent” due to its flexible molecular chain ...

Partial flooding and its effect on the performance of a proton exchange membrane fuel cell
, 2020Water management is one of the key issues for efficient and stable operation of proton exchange membrane fuel cells (PEMFCs). Water flooding easily occurs at the elevated operation current density, especially at the downstreaming of the flow channel ...

Data-driven oxygen excess ratio control for proton exchange membrane fuel cell
Applied Energy, 2018Efficient oxygen excess ratio (OER) control is of great importance for proton exchange membrane fuel cell because it is closely associated with the economic efficiency and safety. As widely investigated, OER control is challenging due to the difficulties

Proton Exchange Membrane Fuel Cells (PEMFCs)
2020Membrane electrode assembly (MEA) is the core component of proton exchange membrane fuel cell, which is composed of proton exchange membrane, cathode and anode catalytic layers and gas diffusion layers. The cost of MEA accounts for more than 60% of that of the total system, and particularly, the cost of platinum (Pt) catalysts accounts for nearly 70 ...
