Abstract
A fuel cell system includes a fuel cell that generates power due to a chemical reaction between fuel gas and oxidant gas, and an ejector that includes a first nozzle and a second nozzle having injection ports with different diameters, respectively, the injection ports injecting the fuel gas. The ejector introduces off gas recirculated from the fuel cell to the fuel cell together with the fuel gas. The fuel cell system also includes a heating unit that heats the ejector. The diameter of the injection port of the second nozzle is smaller than that of the first nozzle, and the heating unit is arranged on the side of the second nozzle of the ejector out of the first nozzle and the second nozzle.

A fuel cell system, comprising:
- a fuel cell configured to generate power due to a chemical reaction between fuel gas and oxidant gas;
- an ejector that includes a first nozzle and a second nozzle having injection ports with different diameters, respectively, the injection ports being configured to inject the fuel gas, the ejector being configured to introduce off gas to the fuel cell together with the fuel gas, the off gas being recirculated from the fuel cell;
- and
- a heating unit configured to heat the ejector, wherein:
- the diameter of the injection port of the second nozzle is smaller than the diameter of the first nozzle;
- and
- the heating unit is arranged on a side of the second nozzle of the ejector, out of the first nozzle and the second nozzle.
