| 摘要 |
A power generation method by a fuel cell power generation system comprising the step of supplying a fuel gas (14a) to a fuel electrode (21) at a low pressure via a fuel gas passage (14), the step of supplying an oxidizer gas (15a) to an oxidizer electrode (22) at a low pressure, the step of reacting electrochemically the fuel gas (14a) with the oxidizer gas (15a) to generate power, and the step of controlling a fuel efficiency at the fuel electrode (21) so as not to cause blocking of the fuel gas passage (14) due to water condensation, thereby hardly lowering performances and deteriorating materia ls locally, and requiring no large turndown ratio for constituent units.</SDOAB > |
