Device for treating exhaust gas from fuel cell

An apparatus for treating an exhaust gas from a fuel cell, the apparatus comprising:

• a tube member discharging the exhaust gas from a fuel cell stack;
• a gas guide portion provided in the tube member and guiding a target gas contained in the exhaust gas to an outside of the tube member;
• and
• a guide tube spaced from the gas guide portion with a first gap and provided to cover the gas guide portion with the first gap,
• wherein a mixing space fluidically-communicating with the outside of the tube member is defined between the gas guide portion and the guide tube, and first and second distal end portions of the mixing space in a longitudinal direction of the tube member fluidically communicate with the outside,
• wherein an outside air is introduced into the first distal end portion of the mixing space, the target gas and the outside air are mixed in the mixing space, and a gas mixture made by mixing the target gas and the outside air is discharged to an outside of the guide tube through the second distal end portion of the mixing space,
• wherein the tube member includes:
• a first tube;
• and
• a second tube provided to be spaced from the first tube with a second gap, and
• wherein the guide tube is provided to be spaced apart from an outer surface of the first tube and an outer surface of the second tube with the first gap.
