Ethylene glycol as fuel for alkaline fuel cells

Homogeneous Catalysis for Sustainable Energy: Hydrogen and Methanol Economies, Fuels from Biomass, and Related Topics

“…The use of ethylene glycol as a fuel in fuel cells has attracted significant interest recently. , In addition to potential application in the energy sector, ethylene glycol is a valuable chemical feedstock with applications in the manufacture of polyesters, e.g., PET resins (polyethylene terephthalate), and as a solvent and antifreeze agent . Current industrial production of ethylene glycol involves oxidation of ethylene to ethylene oxide under harsh reaction conditions followed by hydrogenation.…”

Ethylene glycol electrooxidation in alkaline medium at multi-metallic Pt based catalysts

“…Desired amount of metal salts were dissolved in order to obtain the following nominal atomic compositions Pt, P 0.5 tPd 0.5 , Pt x Bi 1Àx (with x from 0.9 to 0.7) and Pt 0. 45 [20]. Accurate amount of carbon (Vulcan XC72) was added directly in the solution to obtain the desired catalyst loading expressed in wt.% and the mixture was kept under stirring for 2 h. The mixture was filtrated on a Durapore Ò membrane filter 0.22 mm (Millipore).…”

“…It is less toxic than methanol; its specific energy is close to that of alcohols (5.2, 6.1, and 8.6 kWh/kg for EG, MeOH and EtOH, respectively [19]) and both carbons carry alcohol group. It can then be assumed that oxidation into oxalate species (COO À -COO À ) can be achieved, as proposed by some authors [20][21][22][23]. Then, 8 moles of electrons are exchanged per mole of EG, instead of 10 for complete oxidation into CO 2 , which means a faradic efficiency of 80%.…”

“…Its specific energy is close to that of alcohols (5.2, 6.1, and 8.6 kW h/kg for EG, MeOH and EtOH, respectively [6]) and both carbons carry alcohol groups. Therefore, as proposed by some authors [7][8][9][10], it can be assumed that the oxidation of EG into oxalate species (COO − -COO − ) can be achieved. Then, 8 moles of electrons are exchanged with 1 mole of EG, instead of the 10 moles required for complete oxidation into CO 2 , which means a faradic efficiency of 80%.…”
