Imaging systems (e.g., printers and copiers) typically include paper paths through which print media sheets (e.g., sheets of plain paper) which are to receive an image are conveyed and imaged. The process of inserting sheets into the paper paths and controlling the movement of the sheets through the paper paths to receive an image on one or both sides, is referred to as “scheduling.”
Electronic printing systems typically employ a print server or scanner for inputting image-bearing documents and conversion electronics for converting the image to image signals or pixels. In the case of electrophotographic printers, the signals are stored and are read out successively to a printer for formation of the images on photoconductive output media such as a photoreceptor. When multiple jobs are to be sequentially printed, a process known as “job streaming” is commonly implemented. Job streaming is the ability of a printer system to complete successive printing jobs with a minimum of delay time between jobs. A control system associated with the image output terminal of the machine identifies that multiple jobs have been scheduled, determines their characteristics and determines the necessary delay between jobs. In some cases, the control system will enable a second job to begin printing prior to completion of the first job. 1. Technical Field

Due to an increasing demand on the earth's limited energy resources and to low conversion efficiencies of conventional power generation systems as well as environmental concerns, the need for a clean and reliable, alternative source of energy has greatly escalated. Fuel cells have been considered for power generation applications for years. Many innovative improvements in operational performance capability have been achieved. Efficiencies have been increased; water-management problems have been resolved; and the use of proton exchange membranes with reduction of the thin film catalyst layers has been achieved.
Fuel cell assemblies with proton exchange membrane cells, in which a hydrogen-oxygen reaction is employed for power generation, have become a popular source of energy in an automobile industry. Unfortunately, the development of suitable stacked assemblies using the proton exchange membrane fuel cell has been subject to various problems, mainly related to corrosion and leakage.
To obviate the corrosion problem, proton exchange membrane (PEM) fuel cells have been overwhelmingly manufactured with bipolar plates made from graphite, not metal. However, increased

 Imaging systems (for example, printers and duplicator) typically include paper path through which photographic print media sheet (e.g., sheets of plain newspaper) which are to receive an image are bring and image.

 Electronic impression systems typically hire a print server or scanner for inputting image - give birth documents and conversion electronics for converting the image to image signals or pixel. In the event of electrophotographic printers, the signals are stored and are read out successively to a printer for formation of the images on photoconductive output media such as a photoreceptor. When multiple jobs are to be consecutive print, a process sleep together as “ caper streaming ” is commonly implemented. Job cyclosis is the ability of a printer system to dispatch successive printing jobs with a minimum of delay meter between jobs. A control system associated with the image output terminal of the machine identifies that multiple jobs have been scheduled, settle their characteristics and decide the necessary delay between jobs. In some cases, the control system will enable a second job to get down printing prior to completion of the first job. 1. Technical Field
