Patent number: 8974556Abstract: Disclosed is a hydrogen generator that prevents the reformate water from bypassing the evaporator in a hydrogen generator, and the occurrence of sudden temperature changes within an evaporation flow path. The hydrogen generator comprises: an evaporator that produces a mixed gas by mixing a raw material gas containing methane with water vapor; a reformer that changes the mixed gas into a hydrogen-containing gas through a steam reforming reaction; and a combustor that supplies heat to the evaporator and the reformer. The evaporator comprises: an inner cylinder; an outer cylinder enclosing the inner cylinder; and a middle cylinder that is inserted between the inner cylinder and the outer cylinder, and that defines a helical flow path between the inner cylinder and the outer cylinder, through which water supplied from the outside flows.Type: GrantFiled: May 20, 2011Date of Patent: March 10, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Kouji Tada, Masaki Nobuoka, Kazuya Shima

Patent number: 8398731Abstract: A fuel treatment device includes: a reforming section that produces a hydrogen-rich gas containing carbon monoxide and water; a converting section that produces a hydrogen-rich gas containing a lower concentration of carbon monoxide by reacting the carbon monoxide and the water in the hydrogen-rich gas; a mixing channel that produces a mixed gas by mixing the hydrogen-rich gas containing the lower concentration of the carbon monoxide with air containing oxygen; an air supplying section that is connected to an upstream end of the mixing channel and supplies the air to the mixing channel; and a selective oxidizing section that is connected to a downstream end of the mixing channel and converts the mixed gas into a fuel gas by reacting the carbon monoxide and the oxygen in the mixed gas, wherein the mixing channel includes a gas supply region at the upstream side and a gas diffusion region at the downstream side, and has two or more gas supply ports connecting the gas supply region with the converting section, aType: GrantFiled: May 26, 2009Date of Patent: March 19, 2013Assignee: Panasonic CorporationInventors: Masaki Nobuoka, Hiroyuki Nagai, Kazuya Shima, Miyuki Yoshimoto, Masayasu Miyazaki
