Stability test terms Links

Owing to their cross-linked network, thermosetting resigns are principally known to be less susceptible to corrosion than some thermoplastic materials. Nonetheless, as shown by Bornbaum (2010), a prediction of long-term stability of polymers in fuel cell operation is hardly possible. Thus, the immersion or accelerated lifetime test should be applied on every novel material which has not been operated successfully in a fuel cell over a several thousand hours. These tests may save considerable amounts of time and can be performed before a fuel cell is set up. Nevertheless and finally, only a long-term test in fuel cells at various parameters and different conditions can provide ultimate certainty as to whether a newly developed composite is suitable or not.
