(PhysOrg.com) -- Hydrogen fuel cells, in which the chemical energy of hydrogen is converted into electricity, offer the potential for a wide variety of applications, especially in transportation and power generation. Although hydrogen fuel cells are currently used on a small scale, making them commercially available for large-scale use requires improvements in two key areas: efficiency and cost-effectiveness.
Microbial fuel cells (MFCs) have the potential to generate electricity while simultaneously providing secondary treatment to wastewater. In a typical application, a microbial fuels cell converts chemical energy to electrical energy ... Read Post
Materials scientists have demonstrated a solid-oxide fuel cell that converts hydrogen into electricity but can also store electrochemical energy like a battery. This fuel cell can continue to produce power for a short time after its... Read Post
(Phys.org) -- Fuel cells, which generate electricity from the chemical energy of a fuel such as hydrogen, are not intrinsically capable of storing energy. When a fuel cell’s hydrogen supply runs out or is temporarily interrupted, th... Read Post
