FUEL CELL APPARATUS AND METHOD OF FABRICATION

摘要

A fuel cell is described. The fuel cell includes current collectors, each of which includes a substrate of lightweight material, such as Kapton material. Micro channels are formed via laser machining or chemical etching into the substrate. The current collectors further include conductive layers sputtered on the substrate, and protective coating on the conductive layers. A variety of materials are available for the conductive layers. The fuel cell so developed is particularly well suited to mobile applications, such as electronic devices.
