Improvement of PEMFC performance with Nafion/inorganic nanocomposite membrane electrode assembly prepared by ultrasonic coating technique

A Nafion-Ceria Composite Membrane Electrolyte for Reduced Methanol Crossover in Direct Methanol Fuel Cells

“…The composite membranes showed a better stability at this temperature compared to pristine Nafion. This can be attributed to the presence of the ceramic fillers and their close interaction with the hydrophobic Nafion backbones [25]. The thermal degradation of pristine Nafion membrane concurs with the literature reports [26] and all the membranes retain up to 90% of their original weight until 300 °C in which the fuel cell operating temperature falls.…”

Enhancement of PEM fuel cell performance at higher temperatures and lower humidities by high performance membrane electrode assembly based on Nafion/zeolite membrane

“…i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y x x x ( 2 0 1 5 ) 1 e8 composite membrane was similar to that of recast-Nafion membrane, but the major decomposition temperature of the polymer main chain shifted to a much higher temperature region [31,32]. This could be attributed to the strong interaction between hydrophobic Nafion backbones and zeolite particles.…”

Self-humidifying Pt–graphene/SiO2 composite membrane for polymer electrolyte membrane fuel cell

“…These described the use of nano-sized inorganic fillers in the membrane to enhance water retention and even to create in situ water production. Nano-sized fillers such as TiO 2 [14,15], TiSiO 4 [16], SiO 2 [17,18], zeolite [19,20], montmorillonite [21] and ZrO 2 [22] were dispersed in Nafion membrane. It has been known that inorganic fillers in polymer inorganic composite membranes contribute to the enhancement of proton conductivity by retaining water within the membrane as well as mechanical and thermal stability [23][24][25].…”
