water-gas shift membrane reactor(WGSM)

Explanation:

The major component in the processing train for fuel cells is the water-gas shift membrane reactors. Fuel cells offer a very clean and environmental source of energy production. They are usually tagged the future of energy production in the world.

  • Unlike the internal combustion systems that uses fossil fuels to produce energy, the water-gas shift membrane reactor allows for the production of energy using the combination of oxygen and hydrogen in the presence of a catalyst.
  • In the reactor, hydrogen gas is a able to readily diffuse out while the other components are unable to do so.
