(JP5043201-A)      Shift reactor unit filling shift catalyser on plate component, and preheater unit arranging heat transferring accelerator material for lowering heat generated by exothermic reaction at the shift reactor unit, are laminated alternately. Cooling medium is supplied to the preheating units and reforming gas contg. CO in several to ten several % is supplied to the shift reaction units. When shift reaction is performed, exothermic heat is rapidly reduced, and the reform gas is exhausted in state of contg. CO not more than 1%.    ADVANTAGE -   Useful for reducing CO in fuel gas, and pollution of electrode of phosphoric acid type fuel cell is prevented    (JP5047402-A)      A fuel cell generator comprises a plate reformed to reform raw material gas to fuel gas with a reforming chamber laid on a fuel chamber, a plate shift convertor provided with the shift reaction section and the gas preheating section and a plate heat changer formed with the hot sections and the cool sections alternately laminated via partition plates.    ADVANTAGE -   The generator has a close configuration of individual equipment allowing easy piping and reduced heat radiation loss.    (US5270127-A)      A plate shift converter comprises a stack of reactor plates (31) each sandwiched between two cooling plates (32) and including a peripheral masking frame (34) with opposed gas inlet (35) and outlet (36), and shift catalyst (41) in the frame. Each cooling plate similarly has a masking frame (44) with opposed gas inlet (45) and outlet (46). There are two pairs of gas intake and exhaust manifolds (53-56) for the reactor and cooling plates respectively, mounted to lateral faces of the stack.    The catalyst may be placed between entrance and exit side partition elements (37,38) which are parallel to each other, and there is a port in the frame between the elements for loading and unloading catalyst. The plates are pref. welded, soldered or brazed together and the manifolds are welded to the stack.    USE/ADVANTAGE -   Used partic. as a power generation system using a phosphoric acid fuel cell stack, provides compact individual units with simple connections and small heat loss.    (JP3114270-B2)      Shift converter comprises stack of alternate shift reactor plates (31) and cooling plates (32) and gas intake and exhaust manifolds (53,55,54,56) mounted on the lateral faces of the stack. Each shift reactor plate includes a plate member (33), with a peripheral masking frame (34), gas entrance (35) and opposite gas exit (36) formed in the masking frame and a shift catalyst (42) also formed in the frame.    Each cooling plate includes plate member (33), masking frame (44), gas entrance (45) and exit (46).    USE/ADVANTAGE -   Esp. in an H3PO4 fuel cell. Gases introduced to the shift reaction plate undergo shift reaction while being cooled by the sandwiching cooling plates. The stack units are compact, piping is simple and heat losses are small.    The cooling plates include a fin plate (47) located in the masking frame. Each shift reactor plate is sandwiched between two cooling plates, the plates being soldered, welded or brazed together to form an integral body. The shift reactor plate includes two side partition elements (37,38) and an intermediate partition element (not shown) extending parallel to each other and each having a loophole structure; the upstream side shift catalyst is placed between the entrance side and intermediate partitions and the downstream side shift catalyst is placed between the intermediate and exit side partitions. Power generation system comprises a housing contg. a pile made up of a plate type reformer, plate type heat exchanger, plate type shift converter and H3PO4 fuel cell stack.
