Abstract
In a shift converter for catalytically converting carbon monoxide and steam to carbon dioxide and hydrogen through exothermic reaction in a phosphoric acid fuel cell apparatus, the heat generated at the shift reaction is absorbed in vaporization of a liquid in a vessel provided with a reactor tube as a heat source. The catalytic exothermic reaction is carried out with cooling in the present invention, and thus it is not necessary to provide coolers at a plurality of stages in contrast to the conventional shift converter.
