TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The heating channel comprises a straight blocking plate having a heating channel separating plate on both front ends, and a heating channel heat conductive fin inwardly extend along the longitudinal direction of the straight blocking plate and front of the heating channel separating plate to facilitate heat transfer of the exhaust gas. The reaction channel seals the front of the reaction channel separating plate and provided with a rectangular blocking plate formed with a partition wall at the center of the mixed gas moving unit to form an independent structure in the reforming reaction chamber and inside the humidification chamber. The rectangular blocking plate is equipped with the fuel inlet portion, the hydrogen gas discharging unit, a fuel inlet groove having an opening and communicating with the catalyst discharge port, a hydrogen gas discharge groove, a catalyst discharge groove, a mixed gas discharge groove and a mixed gas inlet groove having the partition wall along the inward direction of the mixed gas moving unit to introduce the mixed gas of the humidification chamber into the reforming reaction chamber. The upper side of the humidification chamber is provided with a water inlet through hole coupled with one side of the injection pipe, and a preheating groove formed with multiple discharge holes and multiple S-shaped flow passages at the inner bottom to discharge hot water or steam into the humidification chamber and communicating with the end of the water inlet through holes. The humidification chamber comprises a humidification chamber heat conductive fin extend along the longitudinal direction promote the heat transfer of the exhaust gas and discharge of the mixed gas and inflow of fuel. The reforming reaction chamber comprises an upper heat conductive fin corrugated with the reforming chamber and inclined towards the upper side from the bottom side of the mixed gas inlet groove to facilitating the heat transfer of the exhaust gas, a catalyst layer to accommodate the catalyst and generate hydrogen gas from the mixed gas at the lower portion of the reforming reaction chamber upper heat conductive fin, and a reforming reaction chamber lower heat conductive fin inclined towards the upper side of the hydrogen gas discharge groove from the lower side of the catalyst discharge groove to promote heat transfer of the exhaust gas at the lower portion of the catalyst layer.
