“…However, the concept of methanol fuel cells started to be investigated in the [24] as well as by Pavela [25]. Accordingly, much research on the anode and cathode electrocatalysts for such an application was initiated at the same time [1,26]. Alkaline electrolytes were initially used for methanol fuel cells; the search for the active anode and cathode catalysts mainly regarded nickel or platinum for the MOR and silver for the oxygen reduction process [25,26].…”

Alkaline electrolytes were initially used for methanol fuel cells; the search for the active anode and cathode catalysts mainly regarded nickel or platinum for the MOR and silver for the oxygen reduction process [25,26]. Parallel investigations of the MOR were conducted in acidic electrolytes such as sulfuric acid in the same period [3,23].…”

“…The electrolytes that were first used in DMFC devices in the 1950s consisted of a concentrated alkaline solution for example, KOH which contained dissolved methanol [3,25,26,93,94]. Although some attempts were also carried out with anion exchange membranes onto which the electrodes were pressed [95], using an approach similar to the modern PEMFCs, the best results in terms of output power were achieved with 5 M KOH [94].…”

“…However, the enhanced reaction kinetics may allow the use of cheaper materials and, possibly, non-noble metals. In alkaline media, Ni anodes and Ag cathodes represent a suitable compromise in terms of activity and cost [25,26,50]. In general, a significant reduction of the catalyst cost may be envisaged.…”

Several prototypes of alkaline DMFC were reported during the 1950s, using porous nickel [14], platinized porous carbon impregnated with Ag-Co-Al mixed oxides [15] anodes, yielding maximum power below 3 mW.cm…”

Fuel cells are strongly linked to renewable energies, particularly to the so-called "Hydrogen Economy". For decades the development of fuel cells able to convert hydrogen and oxygen in electrical energy with water as unique byproduct has motivated huge activity in fundamental and applied electrochemistry.In this chapter we introduce the concept of methanol economy and discuss its status and perspectives. To be a reality the methanol and other alcohol economies depend on the development of alcohol feed fuel cells, whose components, operation modes and general performance are analyzed. World Energy Consumption: Current Status and TendenciesThe Stone Age did not end for lack of stone, and the oil age will end long before the world runs out of oil. Sheikh Ahmed Yamani (former Saudi Arabia's Oil Minister)The world energy consumption at the beginning of this decade was 12 billion tonnes of oil equivalent (toe), 1 and 87 % is generated by burning fossil fuels (oil 33.7 %, natural gas 23.6 % and coal 29.7 %) [1], which are non-renewable and increase the CO 2 content of the atmosphere, considered as the major man-made Around a half of the world energy demand corresponds to developed countries that originally signed the Convention on the Organisation for Economic Cooperation and Development (OECD), including United States, Canada, Japan and European Community. An important fraction of the other half is consumed by Russia and the fast-developing countries; particularly China and India, being coal, the worst fossil fuel in terms of CO 2 emissions, and the most vastly employed in these highly populated regions.An important fraction, close to 40 % of the fuel resources is used for power generation, while industry and transport demand around 30 % and 20 %, respectively [1,2]. Projections of energy demands for the next decades is a subject that concerns oil-related industries [2-4], governments and energy planners. British Petroleum projections till 2030 [2] are summarized in Fig. 1.1, where the growth in energy demand is basically modulated by the growth of the population and gross domestic product (GDP), mainly due to the contribution of the non-OECD countries. By 2030, 1.3 billion more people will need energy; and the world income is expected to roughly double the 2011 level.The raise of fossil fuel prices to record levels in real terms over the past decade inevitably lead to supply responses, by development and deployment of new technologies across a range of energy sources. Thus, the "shale revolution", first for gas and then for oil, will allow account for almost a fifth of the increase in global energy supply to 2030 [2]. Simultaneously, high prices for fossil fuels will also support the expansion of biomass renewable energy supply, accounting for 17 % of the increase in global energy supply by 2030. Hydro and nuclear together will
