Some of the text related to CWR, ITM & AFC which the article refers to:
How does it work?
Simply put, fuel cells take in oxygen and a gas – usually, hydrogen, although others can be used – and combines them through an electrochemical reaction, creating water and electricity. As nothing is burned, no pollutants are released.
There are a number of different types of fuel cell, each with differing advantages. Ceres Power, for example, makes a fuel-flexible cell that can run on natural gas, biogas, hydrogen or other fuels. AFC Energy (AFC) makes an alkaline fuel cell that uses lower-cost components and runs at a lower temperature.
However, the hydrogen economy extends beyond fuel cells. Electrolysers, such as those made by UK-listedITM Power (ITM), split water into oxygen and hydrogen, allowing it to supply hydrogen refuelling stations for fuel-cell vehicles. It can also convert surplus electricity into hydrogen and methane, which can be stored in existing gas networks.
