Abstract
A fuel cell system comprises a reformer () which produces reformate gas containing hydrogen using gas containing oxygen and raw material vapor, and a fuel cell () which generates power by reacting hydrogen in the reformate gas with oxygen. A controller () determines whether or not excess hydrogen has been produced by the reformer (), and when it is determined that excess hydrogen was produced, burns the excess hydrogen to keep the reformer () warm.
