This paper reports performance data for the direct methanol fuel cell (DMFC) using membrane electrode assemblies using radiation-grafted proton exchange membranes based on polyethylene and ETFE. These membranes exhibited low methanol diffusion coefficients and were thus felt to be potentially useful in reducing possible methanol cross-over from anode to cathode. The membrane electrode assemblies were based on Nafion ® -bonded carbon-supported catalyst; platinum/ruthenium for the anode and platinum for the cathode. The cell voltage performance of the DMFC, for short duration (<100 h) testing, with these low cost membranes is as good as, or superior to, that of cells based on Nafion ® under identical operating conditions. However, the stability of contact between the membrane and the catalyst layer requires improvement before these membranes become real alternatives to materials such as Nafion ® , for the DMFC.

Abstract. Fuel cells, as devices for direct conversion of the chemical energy of a fuel into electricity by electrochemical reactions, are among the key enabling technologies for the transition to a hydrogen-based economy. Among the various types of fuel cells, polymer electrolyte membrane fuel cells (PEMFCs) are considered to be at the forefront for commercialization for portable and transportation applications because of their high energy conversion efficiency and low pollutant emission. Cost and durability of PEMFCs are the two major challenges that need to be addressed to facilitate their commercialization. The properties of the membrane electrode assembly (MEA) have a direct impact on both cost and durability of a PEMFC.An overview is presented on the key components of the PEMFC MEA.. The success of the MEA and thereby PEMFC technology is believed to depend largely on two key materials: the membrane and the electro-catalyst. These two key materials are directly linked to the major challenges faced in PEMFC, namely, the performance, and cost. Concerted efforts are conducted globally for the past couple of decades to address these challenges. This chapter aims to provide the reader an overview of the major research findings to date on the key components of a PEMFC MEA.

Bio-inspired materials or natural biopolymers have attracted much attention for industrial applications as biocompatible materials. Although these materials have been discarded as industrial waste around the world, there is an increasing interest in environmental, engineering, and electrical applications of the biomaterials because of their well-controlled structures and superior conducting properties. The controlled structures of the hydrogen-bonding network in biomolecules, such as bioenergetic proteins, are essential for efficient energy transduction in living systems and application of a biomolecular mechanism could make it possible to prepare efficient electrolytes with superior conducting properties. We report here a recent investigation on the new class and new concept of electrolyte materials with bio-inspired molecular architectures of acid-base pairs for anhydrous proton conduction and its application in intermediate temperature C) polymer electrolyte fuel cells (PEFC). Although some membranes were composed from entirely biomolecular materials, they showed large anhydrous proton conductivities from room temperature to 160 C, and fuel cells employing biomembranes as a polymer electrolyte produced electrical power under non-humidified H 2 /O 2 condition at 160 C. These bio-inspired materials may have many potential applications not only because of its superior ion conducting properties, in particular, under anhydrous (water-free) or extremely low-humidity conditions, but also because of its biocompatibility.Increasing interest toward the global sustainable energy has occurred in relation to political, economical, and environmental protection aspects, whereas, from an industrial development point of view, advanced energy technology is becoming intensively important recently in ordered to reduce fossil fuel consumption and keep the environment clean for human activities. The Kyoto protocol has stimulated research activities in renewable energy technology in every nation and every industrial sector. Among them, polymer electrolyte fuel cells (PEFC) have been recognized as most promising energy conversion devices because they are much very efficient and emit less of CO 2 from automobile, terrestrial, and industrial power sources.
