The research aims to study the effect of the distribution water on
Proton Exchange membrane fuel cell (PEMFC), and the
relationship of membrane thickness and the effects of changes in
thickness depending on the amount of water contained within the
membrane. The research also aims to change the effect of humidity
on the effectiveness of the membrane proton through the diffusion
coefficient and the coefficient of the flow electral osmotic. The
research includes the study of humidity on the cell performance at
constant temperature and its effect on the input interface.
