A solid oxide fuel cell system includes a first fuel cell tube, a flame tip protection member and a current conduction member. The first fuel cell tube has a flame end. The flame end has exit opening. The fuel cell tube is configured to deliver combustible gas to the flame tip region generating a flame kernel. The flame protection member is configured to inhibit at least one of mass transfer and heat transfer between the fuel cell tube and the flame tip region. The current conduction member is disposed through the exit opening of the flame end of the first fuel cell tube.
