FRANCO, Juan I; SANGUINETTI, Alfredo R; COLANGELO, Gabino E y FASOLI, Héctor J. Work Conditions and Time Stability Study on a Fuel Cell Stack and its Peripheral Components. Inf. tecnol. [online]. 2010, vol.21, n.5, pp.125-133. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642010000500016.
The development and working performance of a protón exchange membrane fuel cell stack (PEMFCS) which was installed at Base Esperanza belonging to the Argentinean Army in the Antarctic territory is presented. The set designed and installed allows working with mínimum peripherical devices and can be operated and maintained by personnel with basic training. The ohmic resistance of the battery is the same that could be obtained from six elements in series; the Tafel slope is 80 mV/dec. Stability experiments were performed during 2278 hours, and the energy generated was 4.2 kWh.
