Rational design can improve hydrogen fuel cell efficiency

(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.

Researchers led by Stanford engineer figure out how to make more efficient fuel cells

Academics / General Science : Science Codex (yesterday)

Solar power and other sources of renewable energy can help combat global warming but they have a drawback: they don't produce energy as predictably as plants powered by oil, coal or natural gas. Solar panels only produce electricity... Read Post

More efficient fuel cells under developement by engineers

Academics / General Science : Science Daily (yesterday)

Solar panels need sun. Wind turbines need wind. Society needs ways to store and dispense alternative energy. Fuel cells could do this. But their chemical reactions are not fully understood. Researchers have studied a high-efficiency... Read Post

Hydrogen fuel cells provide power when fuel supply is off

Academics / General Science : Physorg Features (2 years ago)

(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
