Preparation of MEA with the Polybenzimidazole Membrane for High Temperature PEM Fuel Cell

Preparation of polytetrafluoroethylene porous membrane based composite alkaline exchange membrane with improved tensile strength and its fuel cell test

“…1(b), the PTFE in the membrane will decrease the conductivity, because it occupies a certain portion of the composite membrane for through plane conductivity, thus the PTFE will show reverse effect on the ionic conductivity. However, it has such a positive effect on the membrane mechanical property [12,15,16] that the membrane thickness can be reduced to 20 mm or 30 mm, which will lead to lower membrane resistance.…”

Recent advances in polybenzimidazole/phosphoric acid membranes for high‐temperature fuel cells

“…Such roll‐to‐roll production may be appropriate for integration with the catalyst‐coated membrane approach, where the catalyst layer is coated on the membrane and doped with PA before assembly with the gas diffusion layer. The catalyst‐coated membrane approach does not require hot‐pressing of the MEA, and thus may circumvent the issue of membrane handling, and it has been shown to give good performance in a fuel cell compared to conventional doping processes …”

Polymer-Layered Silicate Nanocomposite Membranes for Fuel Cell Application

“…PEMFCs operating above 100 C are preferred over that operating at low temperature to overcome several disadvantages (like CO catalyst poisoning and heat and water management) associated with the later [1,6,7,24]. Inferior proton conductivity of Nafion at high temperature and low humidity has prompted towards the development of new polymer membranes such as polyethersulfone (PES) [25,26], polyetheretherketone (PEEK) [27][28][29][30], polyimide (PI) [31][32][33], polybenzimidazole (PBI) [34][35][36][37][38][39][40][41], polystyrene-acrylonitrile (SAN) [42,43], and polyvinylidene fluoride (PVDF) [44][45][46] to meet the U. S. Department of Energy (DOE) targets [47,48].…”
