Solid oxide fuel cell process gas sampling for analysis

A method for monitoring process gas of a solid oxide fuel cell system (10) is disclosed. The method comprises directing a portion of process gas from a chamber (16) of the solid oxide fuel cell system (10) to a main plenum chamber (12). A portion of process gas is cooled to a measurable temperature and directed to a sensor (50) for analyzing. A solid oxide fuel cell system (10) is also disclosed.
