The new hydrocarbon membranes self-assemble proton channels which are smaller than those in previous technologies. That means the polymer matrix is stronger and swells less. The result is that more of the water and methanol remain on the fuel side of the cell, creating more electricity, and leaving behind less heat, water, and CO2. Fuel cell packaging, in turn, can be made smaller, lighter, less expensive, and sturdier.
