A study of the performance of SPEEK electrolyte of a novel PEMFC

Materials Research Express
Abstract Analysis of performance of fuel cell is carried out by considering non-fluorinated electrolyte and variety of potential electrodes. The study spans low temperature regions and carried out MD investigation of transport of ions in a novel PEM fuel cell (PEMFC), which is composed of electrodes and SPEEK as a non-fluorinated ...

SPEEK/Polyimide Blends for Proton Conductive

, 2009
A series of membranes, based on sulphonated poly(ether ether ketone) (SPEEK)/polyimide (PI) blends, was prepared at different casting conditions. They were characterised by SEM, FTIR, DMTA, DSC, TGA, water/methanol pervaporation and impedance spectroscopy.

Functionalized microporous sulfonated polyetheretherketone: Osteogenesis and anti-osteoclastogenesis effects via ROS and NLRP3-mediated pyroptosis in macrophages

Materials & Design
The treatment of osteoporotic implant failures tends to be challenging due to an imbalance in bone homeostasis. Recently, the accumulation of intracellular reactive oxygen species (ROS) and activation of the inflammasome containing nucleotide-binding ...
