(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.
An unappreciated aspect of chemical reactions on the surface of metal oxides could be key in developing more efficient energy systems, including more productive solar cells or hydrogen fuel cells efficient enough for automobiles. 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
