Abstract
A fuel cell includes a substrate having a pair of grooves, an electrolyte membrane lying on the substrate so as to define a pair of flow channels, and catalyst-bearing current collector layer sections disposed on the inner wall of the grooves or the inside surface of the electrolyte membrane defining the channels. A fuel liquid flows through the first channel to undergo anodic reaction, an oxidant liquid in the form of an aqueous hydrogen peroxide solution flows through the second channel to undergo cathodic reaction, and hydrogen ions traverse the electrolyte membrane.
