Research Abstract

Observation of produced water on a fuel channel bottom was demonstrated. It was found that poor performance cell showed significant variation of water production inside the fuel cell chip. Some observations suggested that the residual porous Si between the channel bottom and the catalyst layer had bad impact on the cell performance by blocking fuel supply. Removal of the residual porous Si was attempted and higher performance was demonstrated by the elimination of the residual porous Si.
