    Abstract: PROBLEM TO BE SOLVED: To eliminate the adverse effects of peroxides generated at the cathode of a fuel cell. SOLUTION: The fuel cell 1 has two electrodes 2 and an ion-exchange membrane 6, with each of the electrodes 2 having an electrode catalyst layer 4 and at least one gas passage for a reaction gas 7. The fuel cell contains at least one kind of additive that works to prevent formation of peroxides and/or decompose peroxides. A method is disclosed for using at least one kind of additive inside or over the electrode 2 of the fuel cell 1 having the ion- exchange membrane 6, the electrode catalyst layer 4, and the electrode 2 having at least one gas flow passage for the reaction gas 7. The at least one kind of additive works to prevent formation of and/or decompose peroxides inside or over the electrode 2.

    Abstract: PROBLEM TO BE SOLVED: To provide a method of producing glyoxal diacetal that uses a water- miscible alcohol and permits the continuous operation in high yield. SOLUTION: The reaction of 40-75 wt.% of glyoxal aqueous solution with a monohydric alcohol is carried out in the presence of an acid catalyst to produce a glyoxal diacetal. In this case, a liquid mixture including the alcohol and glyoxal in at least 15:1 molar ratio and water in an amount of ≤8 wt.% at the start of the reaction is brought into contact with an acid catalyst so that the alcohol used may not be distilled off over 5 wt.% until the concentration of the diacetal formed in the reaction mixture attains at least 70% of the equilibrium concentration.

    Abstract: A method for producing alcoxylated carbonyl compounds of general formula (I) (compounds I): R aR C(OR )b wherein R , R represent hydrogen or C1- C6-alkyl, R independently means C1- C6-alkyl, a is 0 or 1, b 2 or 3 with the proviso that the sum of a and b is 3, by means of anodic oxidation of germinal dialcoxy compounds of general formula (II) (compounds II) wherein R , R , R , R represent hydrogen or C1- C6-alkyl, R , R represent C1- C6-alkyl or C1- C6-alcoxy, in the presence of a C1-C6-alkyl alcohol (compounds III).A usual compound (compound IV) is used as a cathodic depolarizer suitable for electrochemical oxidation. The anodic oxidation and cathodic reduction is carried out in an undivided electrolyte cell in the presence of C1-C6-alkyl alcohols.
