    摘要: A novel design and process for: a) a membrane electrode assembly (MEA) with aligned carbon nanotubes as a nano-scale gas distributor which yield better gas conversion efficiencies in PEM fuel cells, and (b) doped silicon flow field plates (FFP) which increase electrode conductivity of the membrane-catalyst-gas diffusion layer (GDL)-FFP interfaces of the proton exchange membrane fuel cell (PEMFC). Also, part of the invention are a stacking configuration and a gas distribution design that also enhance conductivity of carbon/metal catalyst/electrode, GDL, and FFP interfaces surfaces without crushing the FFPs. Aligned carbon nanoscale gas distributors are employed at the interfaces, thereby increasing the overall performance of the PEMFC. The FFPs are easy to manufacture and mass-producible, yet mechanically sturdy and significantly lighter in weigh than their conventional counterparts. Another novel feature of the invention is an integrated monitoring and communication/Internet system located directly or connected to the FFP.

    摘要: Disclosed is a stator structure of a rotary device and its forming method. The method for forming a stator structure includes the steps of (a) forming a first part having a first middle portion with a through hole, and M pieces of extending portions extending from the first middle portion, (b) forming a second part having a second middle portion with a through hole, and N pieces of extending portions extending from the second middle portion, (c) alternately bending the M pieces of extending portions of the first part toward a first direction and alternately bending the N pieces of extending portions of the second part toward a second direction opposite to the first directon, respectively, and (d) correspondingly combining the first and second parts together to form the stator structure in which the bent extending portions of the first and second parts constitute a columnar portion of the stator structure for winding a coil thereon, wherein M and N are even numbers not less than four, respectively.
