Abstract: Liquid fuel is evaporated and mixed with an oxidizing agent in a mixing chamber of a reformer by first introducing substantially only the liquid fuel in an axial downstream direction into a first upstream zone of the mixing chamber via a nozzle so as to atomize the liquid fuel. Then steam is separately introduced into the upstream zone and contacted with the atomized fuel to cause the fuel to evaporate. An oxidizing agent is then introduced downstream of the first zone in a second zone of the mixing chamber to the evaporated fuel and uniformly mixing the oxidizing agent with the evaporated fuel.

Abstract: A bellows unit and a compression coil spring are located in series with each other between a first member and a second member. The bellows unit has an inner bellows, an outer bellows, and first and second end members. A sealed space is defined in the bellows unit. A compressed gas is sealed in the sealed space. The bellows unit is caused to extend and contract in the direction of an axis by the compressed gas. The sealed space contains an uncompressible liquid that can exchange heat with the gas. The liquid is an example of a heat exchange material.
