  • Introduction: Background The vast majority of research into solid-state polymer electrolytes for low-temperature (o200 1C) fuel cells has focused on proton-exchange membrane (PEM) fuel cells (PEMFCs). Recently, there has been interest in the application of the analogous anion-exchange membranes (AEMs), in alkaline forms, in low-temperature fuel cells (Figure 1).

  • The recent fuel cell (FC) development worldwide has always been accompanied by a number of studies and projects investigating the applications of FCs onboard ships. Almost all possible FC types and different fuels such as hydrogen, natural gas (liquefied or pressurized), liquefied pressurized gas (LPG), methanol, and maritime diesel have been considered. These applications of FCs are still mainly focused on onboard power generation (OPU) and propulsion.

  • This should consider that premiums reflect both the first party costs (generally damage to the driver’s own vehicle) and third party costs (generally damage to property outside of the driver’s vehicle and injury costs for people outside of the vehicle although it will, of course, include injury costs for passengers in the driver’s vehicle where the driver is at fault). These new technologies, therefore, need to be able to reduce the casualty rate and the level of severity of collisions.

  • More companies are proving it is possible to make money and actively help to slow the degradation of the planet for future generations. Within these companies, the push for change comes from the top—it’s all about leadership. UTC Power has great success working with organizations whose leaders are visionary about how their business affects the environment. They are concerned about where their companies need to be 3 0 or 40 years down the road. It’s the vision of the leadership that moves them toward using power solutions like ours.

  • As we stated in our 2011 Industry Review, the fuel cell industry began its road to commercialisation in 2007. This process has not been an easy one, with the problems associated with introducing a new technology to the general public (and even to industrial customers) comprising legislative, manufacturing and cost barriers. Slow-but-steady progress has meant that, historically, announcements purporting signifi cant product shipments have tended to disappoint, often experiencing delays or even being cancelled.

  • The Japanese residential fuel cell scheme accounts for the majority of shipments in this application, under the Ene-Farm brand. By 2010, it was clear that the scheme was well on its way to being a success, delivering signifi cant cost reductions and performance improvements and allowing subsidies to come down, and by the end of the year fuel cell heating and power had been brought to over 13,500 households in total. Good growth in sales was expected in 2011, but what no one could have anticipated were the events of March 2011, when the T¯ ohoku earthquake and tsunami struck...

  • Hydrogen, as an energy carrier, is widely regarded as a potential cost effective, renewable, and clean energy alternative to petroleum in order to mitigate energy shortage and global climate warming issues that the world is currently facing. However, storage of hydrogen is a substantial challenge, especially for applications in vehicles with fuel cells that use proton-exchange membranes (PEMs). Therefore, scientific community has started focusing their research activities on developing advanced hydrogen storage materials through nanotechnology. ...

  • In the quest for knowledge, it is not uncommon for researchers to push the limits of simulation techniques to the point where they have to be adapted or totally new techniques or approaches become necessary. True multiscale modeling techniques are becoming increasingly necessary given the growing interest in materials and processes on which large-scale properties are dependent or that can be tuned by their low-scale properties. An example would be nanocomposites, where embedded nanostructures completely change the matrix properties due to effects occurring at the atomic level.

  • Insulin is the principal regulatory hormone involved in the tight regulation of fuel metabolism. In response to blood glucose levels, it is secreted by the b cells of the pancreas and exerts its effects by binding to cell surface receptors that are present on virtually all cell types and tissues. In humans, perturbations in insulin function and/or secretion lead to diabetes mellitus, a severe disorder primarily characterized by an inability to maintain blood glucose homeostasis. Furthermore, it is estimated that 90–95% of diabetic patients exhibit resistance to insulin action....
