Burner

A burner for burning a gaseous fuel containing hydrogen with a gaseous oxidizer containing oxygen comprising:

• a combustion chamber having an inlet side and in which the combustion reaction takes place during operation of the burner, and
• a wall structure, which seals off the combustion chamber on the inlet side and comprises:
• multiple fuel openings through which the gaseous fuel is introduced into the combustion chamber during operation of the burner, and
• multiple oxidizer openings through which the gaseous oxidizer is introduced into the combustion chamber during operation of the burner,
• wherein:
• the combustion chamber is surrounded laterally by an outside wail and an inner wall,
• a cooling space is provided between the inside wall and the outside wall, said cooling space being connected to the multiple oxidizer openings in the wall structure and communicating with the combustion chamber, and wherein
• the wall structure forms one of two end plates of a fuel cell having multiple electrolyte plates between the end plates, with a fuel path and an oxidizer path being provided between said electrolyte plates.
