Abstract:
An alignment device for aligning a second aperture in a second plate with a first aperture in a first plate and an alignment method of utilizing the same. The alignment device includes a main body, a first part extending from the main body, and a second part extending from the first part. The main body comprises a first linear dimension exceeding a width of the second aperture for disposing overlying the second plate. The first part comprises a second linear dimension for extending and fitting into the second aperture. The second part comprises a third linear dimension for extending and fitting into the first aperture.
Abstract:
A method comprises supplying a dopant gas in an arc chamber of an ion source. A dilutant is supplied to dilute the dopant gas. The dilutant comprises about 98.5 wt. % xenon and about 1.5 wt. % hydrogen. An ion beam is generated from the diluted dopant gas using the ion source.

Abstract:
A bipolar plate and a fuel cell are provided. The bipolar plate for the fuel cell has a plurality of flow channels, and a rib is defined between neighboring two flow channels. A top surface of the rib may be a roughened surface or have a porous structure in order to improve performance of the fuel cell.
Abstract:
The present invention relates to a metal catalyst composition modified by a nitrogen-containing compound, which effectively reduces cathode catalyst poisoning. The catalyst composition applied on the anode also lowers the over-potential. The catalyst coupled with the nitrogen-containing compound has increased three-dimensional hindrance, which improves the distribution of the catalyst particles and improves the reaction activity.
