Fuel cells are getting growing interest in industrial areas like backup systems for telecom applications or power source for electric vehicles. Although these systems are characterized by long periods of inactivity, they must be able to start at any instant in the shortest time. However, the membrane of which PEMFCs are made of tends to dry out when not in use. This increases the time interval required to start the system up and could lead to the destruction of the fuel cell. In this article a start-up time measurement setup is presented, which is part of a larger project, the membrane hydration status estimator for monitoring the humidity of a fuel cell stack during standby. The fuel cell has been placed in a climatic chamber, connected to hydrogen and the start-up time has been measured with different environmental conditions. Based on the previous results and the ones presented in this paper a correlation between the start-up time and relative humidity of the membrane can be derived.
