Descripcion del fallo en el sellado en una pila PEM de 7 celdas

Abstract

Este trabajo presenta los datos y la descripción del fallo de una pila PEM debido a la degradación de su sellado. La pila en cuestión es una pila ElectroChem compuesta de 7 celdas. El cambio inexplicable de ciertas variables como la temperatura, la presión y el voltaje indicó un posible fallo de la pila. La pila se monitorizó durante un periodo de seis horas durante el cual se recogieron datos y, posteriormente, se analizaron los resultados adquiridos concluyendo que el fallo de la pila se debió a una fuga cruzada en el sellado del cátodo en la celda #2. Del análisis del fallo en la pila estudiada se pueden deducir una seria de indicadores que pueden ser utilizadas en su monitorización para evitar daños mayores.

This work was supported by the project 'Diseño de controladores para el proceso electroquímico en pilas de combustible de tipo PEM' (4796).

Este trabajo ha sido parcialmente financiado por el proyecto CICYT DPI2004-06871-C02-01, del MEC español.

Presentado al II Congreso Nacional de Pilas de Combustible celebrado en Madrid en 2006.
