Exhaust gas clean-up system equipped with power generating function

An exhaust gas clean-up system equipped with a power generating function, comprising:

• a steam reforming unit to produce hydrogen from exhaust gas supplied,
• a hydrogen permeable membrane configured to allow only hydrogen produced by the steam reforming unit to pass through it,
• a hydrogen storage unit configured to absorb hydrogen supplied through the hydrogen permeable membrane and release absorbed hydrogen,
• a fuel cell configured to generate power using hydrogen supplied from the hydrogen storage unit,
• a gas clean-up unit configured to clean up residual gases not passing through the hydrogen permeable membrane,
• a control unit configured to control the hydrogen storage unit to absorb or release hydrogen depending on whether the fuel cell is supplied with an operative amount of hydrogen,
• a hydrogen delivery path extending from the hydrogen permeable membrane to the gas clean-up unit via the hydrogen storage unit and the fuel cell, and
• a residual gas delivery path extending from the steam reforming unit to the gas clean-up unit bypassing the hydrogen storage unit and the fuel cell.
