Abstract

This invention relates to a fuel cell system with a polyelectrolyte membrane fuel cell and a method by which the pressure inside the fuel cell can be regulated by means of the quantity of fuel introduced. This regulation is accomplished by means of pressure sensors which are controlled by means of an electronic control unit.
