Apparatus and method for supplying fuel to a gas-generating system
An apparatus for supplying fuel to a gas-generating system to generate hydrogen-rich gas in a fuel cell system includes two gas-generating components; a metering device, which can supply fuel by a valve-controlled distribution to each of the two gas-generating components; and a fuel storage basin. The fuel basin which supplies fuel to one of the gas-generating components during a changeover or connecting process between the gas-generating components.
1. An apparatus for generating hydrogen-rich gas for a fuel cell system, comprising:
at least first and second gas-generating components;
a common metering apparatus that can supply fuel to each of the first and second gas-generating components;
a fuel storage basin; and
a valve system operable to permit supply of fuel from the fuel storage basin to the second gas generating component while the first gas-generating component continues to be supplied with fuel by the common metering apparatus and while the first and second gas-generating devices are operated in parallel, and to terminate supply of fuel from the storage basin and to the first gas-generating component when the second gas-generating component reaches its operating temperature.
2. An apparatus according to claim 1 , wherein the valve system comprises:
a first valve connected between the metering apparatus and the first gas-generating component;
a second valve connected between the fuel storage basin and the metering apparatus;
a third valve connected between the fuel storage basin and the second gas-generating component; and
a fourth valve connected between the metering apparatus and the second gas-generating component.
