We have proposed an application of woodceramics sheet to electrode for Polymer Electrolyte Fuel Cell (PEFC). The performance of the PEFC with woodceramics electrodes was experimentally investigated. The woodceramics electrode was made from a paper filter. It was confirmed that the amount of impurities in the woodceramics electrode was very small. The generated power of the PEFC with woodceramics electrodes was almost same as that of the PEFC with carbon paper electrodes. To estimate the influence of the degree K of impregnation of phenolic resin in the woodceramics electrode, we made several woodceramics electrodes with different K. The generated power of the electrode with K of 28.2 % was 0.34 mW/cm^2. It was highest among the electrodes made in this experiment. In case of the electrode with too large K, the output power may be low because of bad gas permeability. On the other hand, If the electrode has too small K, the output power may also · be low. That is because the mechanical strength may decrease with a decrease in K. This means that there may be the optimum K from the viewpoint of the output power.
