Method and apparatus for electrochemical compression and expansion of hydrogen in a fuel cell system
Patent number: 7141323Abstract: The invention relates to fuel cell systems and associated methods of operation where an electrochemical cell such as a fuel cell is used as an electrochemical hydrogen separator to separate hydrogen from a process stream (e.g., reformate or synthesis gas), or as an electrochemical hydrogen expander to inject hydrogen into a process stream. In one aspect, the invention provides a method of operating a fuel cell system, including the following steps: flowing hydrogen from a hydrogen supply conduit through a fuel cell to provide an electric current to a load coupled to the fuel cell; actuating an electrochemical hydrogen separator in a first mode of operation of the system to transfer hydrogen from the hydrogen supply conduit to a hydrogen storage vessel; and actuating an electrochemical hydrogen expander in a second mode of operation of the system to transfer hydrogen from the hydrogen storage vessel to the fuel cell.Type: GrantFiled: August 7, 2002Date of Patent: November 28, 2006Assignee: Plug Power Inc.Inventors: Arne W.

Patent number: 5493076Abstract: The present invention relates generally to a new structure and a method for repairing semiconductor substrates, and more particularly, the invention encompasses a structure and a method for repairing Printed Circuit Boards or other electronic substrates by providing electrical lines on the defective board. On a substrate that has an open or an electrical discontinuity, after the discontinuity has been established, a portion of the electrical line across from the electrical discontinuity are exposed and one or more trenches or grooves are made between the two or more exposed portions of the electrical line. The two exposed portions of the exposed electrical line is then joined by either an electrical wire that is routed through the trench or using a standard deposition process one or more metals or material are deposited in the open trench to provide or restore electrical continuity and the excess deposition material is removed.Type: GrantFiled: January 26, 1995Date of Patent: February 20, 1996Assignee: International Business Machines CorporationInventors: James M.
