Fuel cell system and method for removing residual fuel gas

A fuel battery system capable of quickly consuming residual hydrogen gas even if a surplus power consumption means has a limitation. During shutdown of the system, a fuel battery (10) is made to generate power by using the surplus fuel gas to charge a secondary battery (41), and non-storable surplus power is consumed by consumption means (22, 33, 13). When the surplus power generated by the fuel cell is consumed by the consumption means, any limitation in the system is detected, and the power generated by the fuel battery is changed depending on the detected limitation.

Charging device

When a battery of an electric vehicle charged with an external power source (AC 100 V), the electric vehicle and the external power source are connected with each other by the intermediary of a charging cable. Upon this charging, it is determined whether or not an input voltage from the external power source is 95 V or more. When the input voltage is less than 95 V, that is, a decline of the voltage in the charging cable is large, since a wiring resistance in the charging cable possibly increases, an upper limit of an output power to the battery is reduced. Consequently, the electric power delivered from the external power source can be limited, and thereby excessive heat generation is inhibited and safety is ensured. Furthermore, since the output power is caused to be limited when the wiring resistance possibly increases, the battery can be charged continuously.

Ultralight cooking stove

An ultralight stove comprises a fuel reservoir having a plurality of jet holes in the top through which vaporized fuel escapes and burns, a portion of which is directed toward a heat conducting heat transfer plug, heat from which being conducted through the heat transfer plug to the reservoir where it heats fuel in the reservoir causing increased fuel vaporization that pressurizes the reservoir which in turn causing pressurized fuel to escape through the jet holes resulting in increased heat to the heat transfer plug, the cycle continuing until a fuel consumption and temperature equilibrium is obtained where the heat transfer plug and reservoir reach maximum operating temperatures. A heat transfer conduit internal the reservoir extends centrally in the reservoir generally from the heat transfer plug to or to near the reservoir bottom therein conducting heat from the heat transfer plug to fuel in the reservoir. An external fuel absorber on the reservoir top receives fuel which when ignited initially heats the heat transfer plug to initiate stove operation such that before fuel in the external fuel absorber is spent, fuel in the reservoir is sufficiently heated to cause vaporized fuel to jet from said portion of the jet holes and be ignited. An internal fuel absorber internal the reservoir on the reservoir bottom in contact with the heat transfer module such that heat is transferred to the internal fuel absorber and any fuel in the internal fuel absorber.
