FUEL UNIT, GAS GENERATOR AND SYSTEM

摘要

Disclosed is a fuel unit for a gas generator such as a hydrogen gas generator that can supply gas to a gas consuming system such as a fuel cell system. The fuel unit includes a housing containing a solid fuel composition (20) and a heat producing material (22). The fuel composition contains gas releasing solid material that reacts to release gas when heated. The heat producing material reacts exothermically to produce heat. A plurality of quantities of the heat producing material are in thermal communication with corresponding portions of an unsegregated quantity the fuel composition such that, following initiation of a reaction of each quantity of the heat producing material, the quantity of heat producing material will heat the corresponding portion of the unsegregated quantity of the fuel composition, and the corresponding portion of the unsegregated quantity of the fuel composition will react to release a quantity of the gas.
