摘要： A power system with a fuel cell array is integrated with power, conversion and control circuitry forming an assembly on a single chip. The power system may include mounted discrete components or flip chips. The power transistors may be built with contacts on both top and bottom of the chip, where the large area on the bottom allows for high power dissipation and current densities. Electrical connections are made between the components by etched runs or integrated layers, as is typically found in integrated circuits. The control functions include controlling the gas flowing in the fuel cell channels in response to the power supplied. Temperature and pressure may be measured and used to optimize the power system operation.

摘要： A fuel cell is provided. The fuel cell includes a power generator incorporated in a housing having air intake ports, an electrical terminal connected to a printed-wiring board, and connectors and a fuel passage for supplying fuel. The terminals are formed in such configurations as to be insertion-mounted on the printed-wiring board or to be surface mounted on the printed-wiring board. The fuel cell is directly mounted on the printed-wiring board. Thus, a cell housing part or a fixing mechanism, a connector, for example, do not need to be provided on an electric device on which the fuel cell is mounted and the structure of the device itself is simplified and miniaturized.

摘要： A micro-electro-mechanical systems (MEMS) based thin-film fuel cells for electrical power applications. The MEMS-based fuel cell may be of a solid oxide type (SOFC), a solid polymer type (SPFC), or a proton exchange membrane type (PEMFC), and each fuel cell basically consists of an anode and a cathode separated by an electrolyte layer. The electrolyte layer can consist of either a solid oxide or solid polymer material, or proton exchange membrane electrolyte materials may be used. Additionally catalyst layers can also separate the electrodes (cathode and anode) from the electrolyte. Gas manifolds are utilized to transport the fuel and oxidant to each cell and provide a path for exhaust gases. The electrical current generated from each cell is drawn away with an interconnect and support structure integrated with the gas manifold. The fuel cells utilize integrated resistive heaters for efficient heating of the materials. By combining MEMS technology with thin-film deposition technology, thin-film fuel cells having microflow channels and full-integrated circuitry can be produced that will lower the operating temperature an will yield an order of magnitude greater power density than the currently known fuel cells.

摘要： Described herein is a process for fabricating microfluidic systems with embedded components in which micron-scale features are molded into the polymeric material polydimethylsiloxane (PDMS). Micromachining is used to create a mold master and the liquid precursors for PDMS are poured over the mold and allowed to cure. The PDMS is then removed form the mold and bonded to another material such as PDMS, glass, or silicon after a simple surface preparation step to form sealed microchannels.
