1.1 Hydrogen Fuel Cells – Basic Principles
A polymer electrolyte fuel cell (PEFC or PEMFC), a phosphoric acid fuel cell (PAFC), a molten carbonate fuel cell (MCFC), a solid oxide fuel cell (SOFC), and an alkaline fuel cell (AFC) are the fuel cells which use principally hydrogen as a fuel. The difference is the electrolyte. ...
The involvement of biological catalysis differentiates them from chemical fuel cells (CFC). BES represents a technology capable to produce power, but also to poise an environmental site at a given redox potential. Moreover, valuable chemicals can be harvested such as hydrogen, methane, organic ...
Nickel-hydrogen cells and, more recently, bipolar batteries have been built by a variety of organizations. The design principles that have been used by the technology group at the NASA Lewis Research Center draw upon their extensive background in separator technology, alkaline fuel cell technology,...
Recently, high solar-to-hydrogen efficiencies were demonstrated using La and Rh co-doped SrTiO3 (La,Rh:SrTiO3) incorporated into a low-cost and scalable Z-scheme device, known as a photocatalyst sheet. However, the unique properties that enable La,Rh:SrTiO3 to support this impressive performan...
