WebA hydrogen fuel cell is an electrochemical cell that produces a current that can work using a spontaneous redox reaction. The net reaction to this is exothermic. The combination of the two half-cell potentials for the electrochemical reaction creates a … WebThe cell. In contrast to indirect methanol fuel cells, where methanol is reacted to hydrogen by steam reforming, DMFCs use a methanol solution (usually around 1M, i.e. about 3% in mass) to carry the reactant into the cell; common operating temperatures are in the range 50 to 120 °C (122 to 248 °F), where high temperatures are usually pressurized..
