How does a methanol fuel cell work?
A direct methanol fuel cell is a variant of a proton exchange membrane fuel cell that uses methanol directly without prior reforming. Methanol is converted to carbon dioxide, protons and electrons at the anode. Like a standard proton exchange membrane fuel cell, protons react with oxygen at the cathode through a proton exchange membrane, and electrons pass through an external circuit to the cathode and work. Basic conditions Total reaction formula: 2CH4O + 3O2 + 4OH-= 2CO32- + 6H2O Positive electrode: 3O2 + 12e– + 6H20 → 12OH– Negative electrode: 2CH4O - 12e– + 16OH~ → 2CO32- + 12H2O Acidic condition CH4 + 2O2 → CO2+2H2O Positive: 3O2 + 12e– + 12H+ → 6H2O Negative electrode: 2CH4O - 12e– + 2H2O → 12H+ + 2CO2 The battery has a desired operating temperature of 120 ° C or less, which is slightly higher than a standard proton exchange membrane fuel cell, and its efficiency is about 40%. A direct methanol fuel cell is a variant of a proton exchange membrane fuel cell that uses methanol directly without prior reforming. Methanol is converted to carbon dioxide and hydrogen at the anode, and like a standard proton exchange membrane fuel cell, hydrogen is then reacted with oxygen.
