Abstract

A method includes (1) operating a fuel processing reactor to convert a hydrocarbon into reformate; (2) flowing reformate through a first pressure regulator to reduce the pressure of the reformate; (3) supplying reformate from the first pressure regulator to a fuel cell to generate electrical power; (4) flowing a portion of the reformate from the fuel processor to a second pressure regulator to reduce the pressure of the reformate while generating the electrical power with the fuel cell; and (5) supplying reformate from the second pressure regulator to the hydrogen purification system while generating the electrical power with the fuel cell.
