| Description | We have developed the technique or pulsed isotopic exchange for investigation fuel cell performance in-situ. This technique involves passing isotopically labelled oxygen over the cathode and looking at how such oxygen is 'scrambled'. This gives us detailed kinetic information on the reduction process at the cathode. |
| Exploitation Route | This method could be put into practice to diagnose problems with cathode performance. |

| Description | This grant allowed us to develop a new technique to measure oxygen exchange within fuel cells. The impact has so far been confined to academia. |

| Title | Pulsed isotope oxygen exchange |
| Description | A short pulse of isotopicallly-labelled oxygen is introduced into a sample environment containing e.g. an oxide with active oxygen capacity. The fate of the oxygen is followed using an on-line mass spectrometer. The oxygen is either lost to the sample, scrambled with normal oxygen or eluted. From the mole fractions in the outlet one can determine rate constant for oxygen uptake and dissociation. |
