Patent number: 5346779Abstract: A reformer arrangement is provided for a fuel cell power generation system in which a raw material gas is reformed with steam to a fuel gas and the fuel gas is fed to a fuel electrode of a fuel cell for power generation. This reformer arrangement includes a main reformer for reforming the raw material gas to the fuel gas; a fuel cell for receiving the fuel gas to cause the power generation and to produce steam; and a second reformer for reforming with the steam non-reformed raw material gas discharged from the fuel electrode. In one embodiment, the second reformer includes a cylindrical or tubular main body. An entrance for the gas discharged from the fuel electrode is formed at one end of the main body, and an exit for the gas is formed at the other end of the main body. The reforming catalyst is placed in a space between the gas entrance and exit, and a lid is provided at one or both ends of the main body for loading and unloading of the reforming catalyst.Type: GrantFiled: June 16, 1993Date of Patent: September 13, 1994Assignee: Ishikawajima-Harima Heavy Industries Co., Ltd.Inventor: Kenzo Nakazawa

Patent number: 5306575Abstract: A fuel cell power plant and a process for operating a series of molten carbonate fuel cells in the fuel cell power plant are described. In the fuel cell power plant, cathode feed gas at required cathode feed temperature is introduced into the cathode inlet of the first fuel cell of the fuel cell series. The cathode exhaust gas from the first fuel cell and the cathode exhaust gas from the exhaust outlet of each successive fuel cell is introduced to the cathode inlet of the next fuel cell downstream thereof. The cathode feed temperature to the inlet of each fuel cell after the first fuel cell is maintained at the desired level by adding a reactant-containing gas to the cathode side exhaust between each pair of consecutive fuel cells in the series. The added reactant-containing gas is at a lower temperature than the cathode side exhaust to which it is added, whereby desired cathode feed temperature to the inlet of each successive fuel cell downstream of the first fuel cell is achieved.Type: GrantFiled: July 17, 1992Date of Patent: April 26, 1994Inventors: Elias H.

Patent number: 5198311Abstract: An LNG cryogenic power generation system using a molten carbonate fuel cell is equipped with a CO.sub.2 separator. The CO.sub.2 separator takes advantages of cryogenic LNG in a manner such that CO.sub.2 among gases discharged from an anode chamber of the fuel cell is liquefied with cryogenic LNG and separated from the anode exhaust gas. Cell reactions take place at a cathode chamber and the anode chamber of the fuel cell to cause power generation as the oxidizing gas which contains CO.sub.2 is fed to the cathode chamber and the fuel gas is fed to the anode chamber. LNG is reformed by a reformer of the fuel cell and the reformed gas is fed to the anode chamber. During the cell reaction, CO.sub.2 of the oxidizing gas fed to the cathode chamber is transferred as carbonate ion to the anode chamber and CO.sub.2 is enriched or concentrated before expelled from the anode chamber. This anode gas is introduced to the CO.sub.2 separator. In the CO.sub.2 separator, CO.sub.Type: GrantFiled: May 22, 1991Date of Patent: March 30, 1993Assignee: Ishikawajima-Harima Heavy Industries Co., Ltd.Inventors: Kenzo Nakazawa, Hiroyoshi Uematsu, Satoshi Hatori
