Scaleup suitability of sulfonated polyether ether ketone membrane‐based microbial fuel cell
Environmental Progress & Sustainable Energy, 2015A sustainable clean energy production from oxidation of biodegradable materials was carried out in a microbial fuel cell (MFC) stack consisting of four MFC units. The stack was fabricated and tested for its scalability using a high engineering, low oxygen mass transfer membrane; namely, sulfonated poly ether ether ketone. Sodium acetate was used as the

AIP Conference Proceedings, 2013
A simple and effective method for the preparation of sulfonated polyether ether ketone (SPEEK) based composites with electrochemical reduced graphene oxide (EGO) as inorganic fillers has been described. The resulting dispersions are homogeneous and the cast membranes show significant improvement on tensile strength and thermal properties.

The influence of blending with Ultem poly(ether imide) (PEI) and doping with HCl and H3PO4 on the properties of sulfonated poly(ether ether ketone) (SPEEK) was studied. Blending with PEI first results in an increase and then in a decrease in membrane swelling at PEI concns. greater than 5%. The elec. cond.
