The solid oxide fuel cell includes a cathode, an electrolyte, and an anode, which are supported on a metallic bipolar plate assembly including gas flow fields and the gas impermeable bipolar plate. The image reading device executes conversion operations with the resolution set. Each ring is associated with a determined transmission power. The encapsulant can be deposited using a wafer level directtop gate molding process or wafer level film assist molding process.
