New research shows that formic acid could be used as a safe,
easy-to-transport source of hydrogen for fuel cells. Matthias Beller and
his colleagues at the Leibniz Institute of Catalysis, in Rostock, Germany, have
found a way to convert formic acid, a common preservative and antibacterial
agent, into hydrogen gas at low temperatures.
While hydrogen produced using this method might not find use
in fuel-cell vehicles anytime soon, the researchers say that the process could
produce sufficient quantities for micro fuel cells
that power portable electronic devices, such as cell phones and laptops.
The challenge of producing, storing, and transporting
hydrogen affordably has kept fuel cells from becoming popular. Instead of
transporting hydrogen gas, it is more practical to have a hydrogen-containing
material that can be broken down to generate the gas where it is needed.
Currently, methane and
methanol top the list of hydrogen sources for fuel-cell vehicles. They are
typically broken down via steam reforming, which requires temperatures of more
than 200 °C and a reforming unit. Read More...
