Study of a PEM Fuel Cell Functioning Performances Using a Test Station
National Institute for Research and Development for Cryogenics and Isotopic Technologies - ICIT Rm. Valcea, Uzinei Street no. 4, P.O. Box Raureni 7, 240050, Ramnicu Valcea, Romania
A PEM fuel cell performances (output power and reliability) are strongly influenced by a series of working parameters, as are cell temperature, input fuel and oxidant gases pressure and humidity. In order to enhance the fuel cell performances, the effects of all those parameters on the cell functioning must be assessed. A test stand for PEM fuel cells stacks of max. output power of 1.5 kW have been designed and built in our institute. It allows the data acquisition and control of cells temperatures, fluids pressure, flow and humidity using adequate transducers, by means of a computer, based on Labview™ software. The obtained experimental results were in good agreement with the model.
