In one disclosed embodiment according to the invention, a fuel cell system
for generating electrical power comprises: an open-ended tubular solid
oxide fuel cell; a first fuel injector tube extending from a first fuel
plenum chamber through one open end of the fuel cell; and a second fuel
injector tube extending from a second fuel plenum chamber through another
open end of the fuel cell; wherein the first and second fuel injector
tubes form a gap within the fuel cell from which a hydrogen-containing
fuel gas may flow towards the open ends of the fuel cell. Further related
systems and method are also disclosed.
