Abstract Ionomers are used in polymer electrolyte fuel cells (PEFCs) catalyst layers to improve proton conduction. Recent analytical studies have clarified that the adsorption of ionomer on surface a Pt deteriorates catalytic activity for oxygen reduction reaction and transport properties near surface. These findings led development new materials, such as mesoporous carbon support highly oxygen...

Low-temperature water electrolysis using an anion conductive polymer electrolyte has several potential advantages over other technologies, however, the fabrication of durable alkaline electrodes remains a challenge. Detachment catalysts results in loss electrochemical surface area. Simple mixtures ionomer and catalyst can suffer from poor adhesion because only physical is used to bind component...

Hydrogen production using anion exchange membrane water electrolysis (AEMWE) offers hope to the energy crisis faced by humanity. AEM can be coupled with intermittent and renewable sources as well use of low-cost electrocatalysts other stack components. In electrolysis, one biggest advantages is transition metal catalysts instead traditional noble electrocatalysts. AEMWE still in its infancy des...

In this study, a series of sulfonated hydrocarbon pentablock terpolymers (NEXAR® Polymers) with different ion exchange capacities (1.0, 1.5, and 2.0 meq g−1) were characterized investigated as membranes ionomers in hydrogen fuel cells. All NEXAR® Membranes exhibited higher proton conductivity (>0.2 S cm−1 at 80 °C, 90% RH) than Nafion (the most frequently used polymer membrane cells). The Membr...

Under clinical conditions, conventional glass-ionomer dental cements can be cured by application of heat from dental cure lamps, which causes acceleration in the setting. In order for this to be successful, such heat must be able to spread sufficiently through the cement to enhance cure, but not transmit heat so effectively that the underlying dental pulp of the tooth is damaged. The current st...
