New Anhydrous Proton Exchange Membrane for Intermediate Temperature Proton Exchange Membrane Fuel Cells

ChemPhysChem, 2011
AbstractHerein, 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.

Large-scale multi-phase simulation of proton exchange membrane fuel cell

International Journal of Heat and Mass Transfer, 2019
Limited by the computational efficiency and stability, traditional 3D (three-dimensional) CFD (computational fluid dynamics) simulations of PEMFC (proton exchange membrane fuel cell) are always in single-channel scale, which neglect the realistic flow ...

Proton Exchange Membrane Fuel Cells (PEMFCs)

2020
Membrane 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 ...
