Abstract:
1. A hydrogen generation assembly, comprising: a fuel processing assembly configured to receive a feed stream and to be operable among a plurality of modes, including a run mode in which the fuel processing assembly produces a product hydrogen stream from the feed stream, and a standby mode in which the fuel processing assembly does not produce the product hydrogen stream from the feed stream, the fuel processing assembly including: a buffer tank configured to contain the product hydrogen stream; a product conduit fluidly connecting the fuel processing assembly and the buffer tank; a return conduit fluidly connecting the buffer tank and the reformate conduit; a tank sensor assembly configured to detect pressure in the buffer tank; a control assembly configured to operate the fuel processing assembly between the run and standby modes based, at least in part, on the detected pressure in the buffer tank; and a return valve assembly configured to manage flow in the return conduit, the control assembly being configured to direct the return valve assembly to allow the product hydrogen stream to flow from the buffer tank to the reformate conduit when the fuel processing assembly is in the standby mode.
