ALD for sustainable future – building a cleaner world from sub-nanometer level

Atomic Layer Deposition (ALD) offers a superior way to coat highly conformal, uniform, pinhole and defect free thin films on even the most challenging nanoscale architectures. The technique is already widely in use in e.g. [...]

Carbon-supported platinum and nickel nanoparticles for CO capture in hydrogen fuel cells

J. D. Durbin D., J. Fermin D., Plana D., J. D. Durbin D., J. Fermin D., Malardier-Jugroot C., Royal Military College of Canada, CA

Fuel cells are electrochemical cells that convert chemical energy into electrical energy with efficiencies up to 80%; they are a promising potential replacement for internal combustion engines in automobiles. However, carbon monoxide poisoning of the [...]

Advanced Catalysts for Fuel-Flexible Fuel Cells

Grant Norton M., Ha S., Marin-Flores O., Fleckner K., Neylon M.K., Breit J., Washington State University, US

In commercial aviation, a concept called the more electric airplane (MEA) will allow greater fuel efficiency by substituting hydraulically and pneumatically driven systems by those based on electrical energy. The increased electrical power demand in [...]

Shape Selective Nano-Catalyst for Direct Methanol Fuel Cells (DMFC) Applications

Hunyadi Murph S., Fox E.B., Serkiz S.M., Colon-Mercado H., Savannah River National Laboratory, US

Direct methanol fuel cells (DMFCs) have recently attracted much interest as a promising alternative to conventional batteries, especially in portable electronic devices. DMFCs, however, have several disadvantages including high cost, largely as a result of [...]

Molybdenum Dioxide: A Reforming Catalyst for Fuel Flexible Fuel Cells

Norton M.G., Marin-Flores O., Turba T.F., Ha S., Breit J., Washington State University, US

Molybdenum dioxide has been shown to be a very active catalyst for the partial oxidation of a Jet A fuel surrogate (n-dodecane). It not only shows a high oxidation activity towards long-chain hydrocarbons, it also [...]

Development of ceramic support for methane reformer from alkali aluminosilicates

Martinello Savi B., Fernandes Silvano W., da Silva L., Bernardin A.M., University of the Extreme South of Santa Catarina, BR

This work deals with the initial development of a ceramic reformer based on alkali metal aluminosilicates coated with nickel for the generation of hydrogen from biogas (methane). The understanding of the microstructural evolution of silicon-aluminum [...]

Nanostructured and Self-Assembled Superhydrophilic Bipolar Plate Coatings for Fuel Cell Water Management

Dadheech G., Abd Elhamid M., Blunk R., General Motors Corporation, US

A stably superhydrophilic coating is required on composite and metal bipolar plates to manage byproduct liquid water and, in turn, to enable good PEM fuel cell performace under low power vehicle operating conditions. Silica-based coatings, [...]

Off-Grid Fuel Cell System for High Power Quality Applications

Lima R.J.S., de Almeida A.T., Mendes A.M.S., Mendes A.M.S., Cardoso A.J.M., University of Coimbra, PT

There is a variety of critical loads, such as information technology, telecommunication, medical equipment and industrial process controls, which require high power quality. Conventional approaches to provide high power quality levels include battery based uninterruptible [...]
