“…Current collector plates in large DMFC stacks are commonly designed and fabricated following the same strategies as for hydrogen fed PEM fuel cells, using graphite as substrate [51,52], although stainless steel anode and cathode current collectors are used in passive stacks [53][54][55]. However, the main interest in the current collector materials and flow fields design is triggered during the last decade due to the increasing interest for the development of micro direct alcohol fuel cells (μDAFC), after Kelley et al fabricated a miniature DMFC [56].…”

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.
