Effect of the fuel electrode composition and structure on the performance of the direct methanol fuel cell

摘要

The effect the composition and structure of the active layer of the anode exerts on the performance of the solid-polymer direct methanol fuel cell is studied experimentally. It is shown that the ohmic voltage losses in the layer and the content of the solid polymer electrolyte (SPE) play an important role. The performance of the fuel cells is the best at 20-25 vol % SPE in the layer.
