PURPOSE:To generate a power of equal voltage on every position all over electrodes by gradually increasing the amount of catalyst carried on electrodes from the intake side toward the outlet side of the electrodes to which reaction gases are supplied. CONSTITUTION:A fuel gas is supplied to a fuel electrode 14, and air is supplied to an air electrode 15 separately to each other, and these reaction gases electrochemically react through a matrix layer 11 to generate a power. In a fuel cell, the amount of catalyst carried on electrodes is increased gradually from the intake side toward the outlet side of the electrodes to which the reaction gases are supplied. Thereby even when hydrogen and oxygen contributing to the electrochemical reaction contained in the reaction gases are consumed with the reaction, so as that the concentration of them is decreased from the intake side toward the outlet side of the electrodes to reduce the output voltage, on the other hand, the amount of catalyst on the electrodes is inversely increased from the intake side toward the outlet side of the electrodes so as to elevate the output voltage, hence as a whole, the generated voltage can be made uniform all over the electrodes. |
