Abstract
A fuel cell power generating system is disclosed in which fuel cells are able to operate with satisfactory and stable cell characteristics for a long period of time even at a high fuel utilization ratio, and which has a high power generating efficiency and a long lifetime. The fuel cell power generating system includes a first fuel cell adapted to be supplied with a fuel gas containing water vapor and an oxidant gas which are subjected to electrochemical and/or chemical reactions for generating electric power, and a second fuel cell adapted to be supplied with the exhaust gas from the first fuel cell and an oxidant gas which are subjected to electrochemical and/or chemical reactions for generating electric power. The humidity of the exhaust gas fed from the first fuel cell to the second fuel cell is appropriately regulated in a manner such that the exhaust gas containing therein an appropriate amount of water vapor is fed to the second fuel cell so as to prevent carbon deposition in the second fuel cell. To this end, a surplus amount of water vapor is removed from the exhaust gas from the first fuel cell.
