The invention relates to a media supply plate () for a fuel cell stack () comprising at least one anode gas terminal () and at least one cathode gas terminal (). According to the invention the media supply plate () further comprises at least one anode waste gas terminal () and at least one cathode waste gas terminal (). The invention further relates to a fuel cell system () using such a media supply plate () as well as a method for producing such a fuel cell system.

Media supply plate for a fuel cell stack

A burner device having a burner chamber () filled at least partially by a porous body (), an evaporation zone () upstream of the burner chamber () for evaporating liquid fuel supplied via a fuel inlet line (), an igniter () for igniting a combustion mixture of evaporated liquid fuel and combustion air supplied via a combustion air inlet line () to the evaporation zone () as well as an exhaust discharge () downstream of the combustion chamber (). A mixing zone () is disposed between the evaporation zone () and the combustion chamber () in which fuel gas is introduced via a fuel gas inlet line () and is mixed with the combustion air and/or the combustion mixture. The burner device can be used as an afterburner in a fuel cell stack.

Burner device with a porous body

A process and device for determination of the lambda value (&#x3bb;) of reformate () which is to be supplied to a fuel cell stack (), by determining the lambda value (&#x3bb;) of the no-load voltage (U) of the voltage on at least one fuel cell element (). Furthermore, a process and device for lambda control of a reformer, utilizes the process and device for determining the lambda value to controller an actuator of a lambda-controlled reformer () for reaction of at least fuel () and air () into reformate (), the reformer being connected to a fuel cell stack () to supply reformate () form the reformer () to the fuel stack ().
