The electro-generative hydrogenation of allyl alcohol (AA) to 1-propanol was studied applying the PEM fuel cell reactor. The results indicated that AA can be converted to 1-propanol at the cathode, and electric power was generated simultaneously. No

The performances of PEFCs operated at low humidity have been greatly improved by the use of catalyst layers containing SiO2 particles (SiO2–CLs). The highest performance was obtained in a cell with SiO2–CLs for both the anode and the cathode, i.e
