A fuel cell was made to allow direct observation of the phenomena and 2-D temperature measurement in cathode channels. The experimental results showed production and flow of liquid water in the cell, and there was good correlation between area covered by condensing water and cell voltage. The experimental results also showed that uniformity of the contact pressure strongly influenced the temperature distribution. Experimental setup was made to measure local current distribution, and it was recognized important to develop a method to compensate the effect of local resistance change due to inserting the measuring probes. The paper proposes an unique method to correct these effect to determine actual local currents.
