“…Many researchers are interested in hydrocarbon polymers with an aliphatic main chain for PEMs. However, this kind of PEM is mainly used for low-temperature PEMFC or DMFC due to the inferior oxidative stability of these aliphatic main-chain hydrocarbon polymers. − The frequently used aliphatic main-chain hydrocarbon polymers include varieties of styrene-based block copolymers, CS, poly(vinyl alcohol) (PVA), and so on. To enhance mechanical strength, methanol barrier, or proton conductivity, these polymers often require doping with inorganic proton-conducting moieties, blending with polymer pairs, or forming into IPNs.…”

Rubber is one of the most versatile materials having myriad of applications-from niche rubber band and eraser to highly engineered spacecraft seal. Of late, the glittering concept of "sustainability" has been able to infiltrate within the domain of elastomer science and technology to a significant extent -in both academia and industry. This fervent context thus necessitates a systematic documentation of brief history, present research scenario and future perspective of sustainable developments in this field. The present review aims to portray a panoramic sketch of various sustainable rubbers and functional rubber additives in this field and intends to provide a direction to their plausible future developments.

“…HPA compounds include a metal (such as tungsten, molybdenum, or vanadium), oxygen, acidic hydrogen atoms, and a element generally from the p‐block (such as silicon, phosphorus) . HPAs have different hydrated structures (Keggin and Dowson Structures), and the Keggin structure (H n XM 12 O 40 ) was a well‐known structure, which consists of a central atom in a tetrahedral arrangement of oxygen atoms surrounded by 12 oxygen octahedra connected with tungsten or molybdenum because its ease of preparation and strong acidity . HPA molecules bridge water moieties through formation of hydronium ions such as H + , H 3 O + , H 5 O 2 + , so HPAs act toward the water of hydration, which is generally loosely bound in the structure for high proton conductivity .…”

This review provides an overview of intermediate temperature proton-conducting membrane electrolyte materials for fuel cells. Such fuel cells operate in the approximate temperature range of 150-300 • C and can capitalize on a number of technological reasons for operating H 2 /air. These reasons include enhancement of electrochemical kinetics, simplified water management, efficient cooling, and useful waste heat recovery. Importantly lower quality, for example, reformed hydrogen, containing relatively large amounts of carbon dioxide, may be used as the fuel. The materials, which have been the focus of intermediate temperature proton-conducting fuel cells, include heteropolyacids, metal pyrophosphates, solid acids, and acid-imbibed high-temperature polymers such as polybenzimidazole.
