As of April 2006, Tekion [16] held the exclusive license to DFAFC fuel cell technology using PEM membranes and formic-acid fuel from the University of Illinois at Urbana-Champaign, and with an investment from Motorola, [17] was partnering with BASF to design and manufacture power packs by late 2007, [18] but development appears to have stalled ...
A fuel cell is an electrochemical energy conversion device. Fuel cells differ from batteries in that they are designed for continuous replenishment of the reactants consumed. This is a partial list of companies currently producing commercially available fuel cell systems for use in residential, commercial, or industrial settings.
The Duffy-Herreshoff DH30 watertaxi is an 18-person hydrogen fueled passenger ship, power-assisted by an electric motor that gets its electricity from a fuel cell.The watertaxi debuted on October 20, 2003 in San Francisco.
Sketch of Sir William Grove's 1839 fuel cell. The first references to hydrogen fuel cells appeared in 1838. In a letter dated October 1838 but published in the December 1838 edition of The London and Edinburgh Philosophical Magazine and Journal of Science, Welsh physicist and barrister Sir William Grove wrote about the development of his first crude fuel cells.
The ideal solid acid fuel cell anode is a "porous electrolyte nanostructure uniformly covered with a platinum thin film". Such electrodes can be prepared by spray drying, e.g., depositing CsH 2 PO 4 nanoparticles and creating porous, 3-dimensional interconnected nanostructures of the solid acid fuel cell electrolyte material CsH 2 PO 4.

On February 1, 2008, Ballard spun out Automotive Fuel Cell Cooperation (AFCC) [3] to allow for further expansion of fuel cell technology. [4] [5] After the split, Ballard continued as a publicly traded company focusing on non-automotive applications (including buses), while AFCC became a privately held company of 150 employees, developing hydrogen fuel cell stacks for automobiles.
Whereas the common PEM fuel cell, also called Low Temperature Proton Exchange Membrane fuel cell (LT-PEM), must usually be operated with hydrogen with high purity of more than 99.9 % the HT-PEM fuel cell is less sensitive to impurities and thus is typically operated with reformate gas with hydrogen concentration of about 50 to 75 %.
Multiple types of solid fuel gasifiers are commercially available for coal, petcoke, and biomass gasification.Designs vary depending on fuel and intended application. As a result, they can differ in the composition of the syngas produced and the efficiency with which they convert coal energy content to syngas energy content - a performance parameter typically termed cold gas efficiency.
