AbstractSince the successful demonstration of alkaline fuel cell technology by Bacon in the 1950s fuel cells – in one guise or another – have held forth the promise of mass market commercialisation. To date this promise has yet to materialise despite the fact that many products are currently undergoing field evaluation and testing. The primary barrier that fuel cell technology must overcome relates to cost but at its heart this is a materials issue. The problems relate to electrolyte and catalyst performance and cost, chemical stability of the cell interconnect and the long-term reliability of fuel and oxidant seals. In this paper, the detailed issues facing the different types of fuel cells will be summarised and an indepth case study on Solid Oxide Fuel Cells (SOFC) will be presented.Keywords: alkaline fuel cell technology Notes1 This paper outlines perspectives in fuel cell materials science by the author.

Abstract This chapter reviews the difficulties encountered in the use of hydrogen as the main fuel in modern fuel cells, and then considers in turn five major types of hydrogen/oxygen fuel cells: the alkaline cell, the phosphoric acid cell, the molten carbonate cell, the solid‐oxide cell, and the solid‐polymer‐electrolyte cell. The direct methanol cell is also described as one using an alternative fuel. The limitations and advantages of each of these cells are described.

An experimental study of an alkaline fuel cell test plant with a 0.5 kW fuel cell module is presented in this paper. The characteristics of the fuel cell module are measured in different steady state load conditions and with different electrolyte temperatures. The results are analysed by calculating the different efficiencies of the module.

Major developments of commercial fuel cells are taking place in the USA and Japan. Alkaline fuel cells are now established for many applications, and multi-megawatt plants based on phosphoric-acid fuel-cell technology are well advanced for commercialisation early in the next decade. Laboratory prototypes of molten carbonate and solid oxide cell systems are being vigorously developed

Abstract This article introduces the radical approach of applying alkaline anion‐exchange membranes (AAEMs) to meet the current challenges with regards to direct methanol fuel cells (DMFCs). A review of the literature is presented with regards to the testing of fuel cells with alkaline membranes (fuelled with hydrogen or methanol) and also to candidate alkaline anion‐exchange membranes for such an application. A brief review of the directly related patent literature is also included. Current and future research challenges are identified along with potential strategies to overcome them. Finally, the advantages and challenges with the direct electrochemical oxidation of alternative fuels are discussed, along with how the application of alkaline membranes in such fuel cells may assist in improving performance and fuel efficiency.
