Improving the Sensoring of PEM Fuel Cell by Numerical Techniques
发布日期 2014
The use of numerical techniques in PEM fuel cell sensoring represents an advantage of project engineering, reducing the costs and accelerating the manufacturing of prototypes. In this work some numerical responses are shown, relating to numerical sensoring of water and oxygen mole fractions at cathode of a 5 cm² of geometric area PEM fuel cell. The need to recognize a geometric figure of merit that meaning the region of sensoring, led us to define the lines localized in the center of the cell. These results allow to predict the behavior of the PEM fuel cell when it works in low temperatures, that is, condition in which the efficiency control is more difficult.
