Abstract

Power unit for an electronic device and process for control and regulation of an electronic device powered by a fuel cell. Power unit includes a fuel cell having a low output voltage between 0.3 and 1V, and a conversion device coupled to the fuel cell to convert an input voltage as low as 0.3 V to a higher output voltage to operate the electronic device.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a Continuation of U.S. patent application Ser. No. 10 / 803,900 filed Mar. 19, 2004, the disclosure of which is expressly incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is directed to an interface device and process for controlling a fuel cell and a device powered by the fuel cell. Moreover, the device communicates with both the fuel cell and the powered device.[0004]2. Discussion of Background Information[0005]An electrochemical fuel cell (FC) is a device that converts the energy of a chemical reaction into electricity. Although fuel cells are increasingly gaining acceptance as electrical power sources, there are technical difficulties that prevent the widespread use of fuel cells in many applications, especially mobile and portable applications. In operation, several problems have been observed, including performance degradation in l...
