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.

Working towards replacing platinum in fuel cells: Performance of iron-based catalysts improved

Academics / General Science : Science Daily (3 years ago)

Researchers have developed a new and improved iron-based catalyst capable of generating even more electric power in fuel cells for transportation applications. Previously, only platinum-based catalysts could produce similar performa... Read Post

New fuel cell keeps going after the hydrogen runs out

Academics / General Science : Science Daily (2 years ago)

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

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
