A perspective on microfluidic biofuel cells:

A fuel cell generates electrical power through electrochemical reactions between a fuel and an oxidant. In order to accelerate its reactions, noble metal catalysts such as platinum are commonly used. At the anode side, the fuel is consumed and oxidized to release electrons that flow through an external wire, while the oxidant is reduced by accepting electrons at the cathode.
