摘要： A fuel cell system comprises: a fuel cell stack having a plurality of unit cells in which anode gas flow paths are formed; an anode gas supply unit configured to supply anode gas to the fuel cell stack via an anode gas supply port of the fuel cell stack; a pressure sensor provided between the anode gas supply port and the anode gas supply unit to measure anode gas supply pressure; a current sensor configured to measure electric current of the fuel cell stack; and a controller configured to control anode gas supply quantity of the anode gas supply unit to thereby control the anode gas supply pressure. The controller is configured to, when there has been satisfied a blockage-predictable condition indicating that occurrence of blockage due to liquid water in the anode gas flow paths of at least one unit cell is predictable, calculate a first pressure for setting a stoichiometric ratio of anode gas to a predetermined value, the stoichiometric ratio being calculated from a current of the fuel cell stack and the anode gas supply quantity, then compare the first pressure with a second pressure for resolving blockage in the anode gas flow paths due to liquid water to determine a higher-in-value one of the first pressure and the second pressure as a selected pressure, and control the anode gas supply quantity so that the anode gas supply pressure becomes the selected pressure.

摘要： A method of fuel desulfurization comprises receiving fuel from a source of fuel in a gaseous phase and condensing the fuel in the gaseous phase in a fuel condenser to convert at least a portion of the fuel into a liquid phase. The method further comprises delivering the fuel in the liquid phase directly to a reformer and returning the uncondensed portion of the fuel in the gaseous phase to the source of fuel to inert the source of fuel.

摘要： A fuel cell separator, a fuel cell stack having the fuel cell separator, and a reactant gas control method of the fuel cell stack are provided. That is, even when the fuel cell stack operates under the low load operation condition, a reactant gas is supplied to the reactant gas passages of the fuel cell separator, and thus, the length of the passage can be shortened by 50% as compared with the prior art having only one reactant gas passage. Therefore, the reactant gas can be effectively supplied without experiencing pressure loss. Further, in the high load operation of the fuel cell stack, the reactant gas is introduced into the first reactant gas passage of the fuel cell separator and utilized in half of the whole electrode area. Subsequently, the reactant gas is introduced into the second reactant gas passage and utilized in the remaining half of the electrode area. The flow rate of the reactant gas flowing along the passage channels is increased by two times, even when the reactant gas utilizing rate is identical as compared with the reactant gas flow in the low load operation. As a result, the moisture existing in the passage channels can be more effectively discharged and the flooding phenomenon occurring in the high load operation can be prevented. By controlling the reactant gas supply in accordance with an operation condition of the fuel cell stack without experiencing pressure loss and deterioration of the utilizing rate, the flooding phenomenon and concentration polarization phenomenon that occur in the fuel cell stack can be prevented.
