As you can see in the figure attached, the alumina tube is a little thicker compared to cell size that is why I attached an alumina-based cap on the top of tube. I used Ceramic Bond 668 to seal it very tight as we use the same ceria bond 668 for sample sealing. For sample, it works perfect but joining these two parts using this ceria bond doesn't work as it shows leakage after heating. So I am looking for your valuable suggestions to counter this leakage problem of my reactor.
Thank you in anticipation.

Yes i think so, actually we are working on reversible protonic ceramic fuel cell and in PCFC mode it doesn't matter a lot if there is a leakage on the anode side, but in PCEC mode hydrogen produced on the anode side and we need to measure the exact amount of Hydrogen produced on the anode side using Gas chromatography (GC) but leakage on the anode side doesn't give us exact amount of hydrogen produced. so that is why I am looking for some recommendations on how to fix the leakage problem.
