Effect of operating temperature on the behavior of promising SPEEK/cSMM electrolyte membrane for DMFCs

Novel nanocomposite membranes based on blended sulfonated poly(ether ether ketone)/poly(vinyl alcohol) containing sulfonated graphene oxide/Fe3O4 nanosheets for DMFC applications

“…The excessive membrane swelling results in membrane fragility which leads to weakness of nanocomposite membrane when incorporated into MEA. 40 As shown in Table 1, a further increase in SGO/Fe 3 O 4 nanosheets content does not improve water uptake, which is due to aggregation of nanosheets in structure of blend membrane. In our previous work, the crosslinked PVA membrane shows a membrane swelling about 30%.…”

“…From the XRD profile, it can be seen that there is a sharp phenyl sulfonated groups on the structure of nanosheets. 40 The absorption peaks at 1023, 1074 and 1247 cm -1 were assigned to the asymmetric and symmetric stretching vibration of O=S=O and stretching vibration of S=O on sulfonic acid groups in SPEEK. The peak at 1631 cm -1 was assigned to the C=C skeletal vibration in the unoxidized graphitic domain.…”

Microbial Fuel Cell Based Polystyrene Sulfonated Membrane as Proton Exchange Membrane

“…The membrane was placed in between anode and cathode. Conductivity data were calculated using equation Generally, there are two types for PEM; porous proton exchange membranes and nonporous membranes called dense membranes (Mayahi et al, 2013). In fuel cells, the major role of dense membranes is to separate the anode and the cathode and to prevent the migration of the anode electrolyte to the cathode compartment as well as preventing the air from moving, which was purged in the cathode compartment, to the anode compartment (Leong et al, 2013).…”

A review on the effect of proton exchange membranes in microbial fuel cells

“…The membrane must have good capability for exchanging protons (Watanabe, 2008). Generally, there are two types for PEM; porous proton exchange membranes and nonporous membranes called dense membranes (Mayahi et al, 2013). In fuel cells, the main duty of dense Table 1 Maximum generated power and current of MFC with different types of mediators and microorganisms .…”
