英文摘要water management is important in the proton exchange membrane fuel cell (pemfc) operations, especially for those cells based on sulfonic acid polymers due to the depending of the conductivity on water. this paper aims at illustrating the effect of the change in membrane water content on cell potential response. for this purpose, the cell potential response has been investigated experimentally and computationally under transient air flow and load change of a pemfc. from the experimental and computational results, an undershoot behavior of cell potential as well as the great influence of the relative humidity on the magnitude of undershoot is observed. it is found that the magnitude of cell potential undershoot increases as the relative humidity decreases. by carrying out a transient simulation on the water content of the membrane, the undershoot phenomena could be well explained. it is also found from the computational prediction that the time scale for the cell potential to reach its steady state is about 20 s, in agreement with experimental results. the model prediction also suggests that the dynamic behavior of pemfc is critically dependent on the water content in the membrane. crown copyright (c) 2010 published by elsevier b.v. all rights reserved.
