    Abstract: A porous gas diffusion electrode for membrane fuel cells on an ion-conducting polymer. The electrode contains a finely divided electrocatalyst which is dispersed in a proton-conducting ionomer and has a total porosity of more than 40 to less than 75%. It supplies considerably improved performance data in comparison to known electrodes. The electrode can be produced by using pore-forming materials which are dissolved during the re-protonation of the ion-conducting polymers with sulfuric acid or are decomposed by the action of temperature.

    Abstract: A fuel cell anode for the oxidation of methanol, which contains at least one platinum metal or alloys of platinum metals as the primary, catalytically active component. The anode is characterized in that it also contains transition metal complexes of phthalocyanine or substituted phthalocyanines as cocatalyst, these amplifying the catalytic effect of the platinum metals and their alloys for the anodic oxidation of methanol.

    Abstract: A braking force distribution linkage for a muscular energy-actuated parking brake system of a motor vehicle, in which the braking force is transferred at least via control cables both to one gear of the vehicle's transmission and to the wheels of at least one driven vehicle axle, the wheel brakes on each vehicle axle being respectively articulated via a compensation element. A linkage, lever and balance arm arrangement ensures a sufficient parking-hold effect on a road surface with differing nonskid properties, even in the event of failure of a portion of the braking system.
