Abstract
A method for supplying air to a fuel cell (), using a controllable air conveying device () which delivers an air mass flow for a cathode chamber () of the fuel cell (), and using at least one air mass flow sensor (). The invention is characterized in that, for at least one location () in the air flow path which is situated at a distance from the at least one air mass flow sensor () in the flow direction, a computed estimate is made of the air mass flow present at that location.
