I have been hearing about a new kind of fuel cell. I'd like to know more.

A fuel cell is an electrochemical device that converts chemical energy from a fuel into electricity. It typically consists of two electrodes (an anode and a cathode) separated by an electrolyte, which conducts protons between them. The electrodes are made of porous materials that allow the reactants to come in contact with each other. When a fuel such as hydrogen or methanol is supplied to the anode, it splits into electrons and protons. These electrons then flow through an external circuit to the cathode, where they combine with oxygen and the protons to form water. This process generates an electric current and also produces heat.
