| 摘要 |
The invention relates to a fuel cell consisting of one or more individual cells, wherein an individual cell is comprised of electrolyte-electrodes unit, means for gas distribution of reactants to the electrodes and an electric contacting of the individual cells. The inventive fuel cell has the following characteristics: the electrodes comprise electrically conductive, regularly disposed micro or nanoscale needle-shaped or tubular-shaped electrode elements affixed on a gas-permeable carrier substrate and coated with a catalyst; the electrode elements are fully or partially surrounded on the outside by the material of the electrolytes; the catalytic reaction zones in the electrode elements are connected to the means for gas distribution by the gas-permeable carrier substrate; the electrode elements are connected to one another and to the electric contacting of the individual cells in an electrically conductive manner.
