Combustor, fuel reforming device, fuel cell system and method for starting up the fuel reforming system

摘要

A combustor (BR) is provided with a premixer (10) mixing fuel and heating gas, a mixer (8) combusting the fuel and the heating gas mixed in the premixer, and a porous medium (9) disposed between the premixer and the mixer. A reformer (2) can be disposed downstream of the combustor, with the combustor and the reformer forming a fuel reforming device (R). Also, a fuel cell (1) can he disposed downstream of the reformer to form a fuel cell system (S), with the fuel reforming device.
