Possibly, my "rubber bible" (= the CRC Handoook of Chemistry and Physics, not a flexible version of the christian holy book!) was too vague when it said "d in air" (ie, decomposes in air), because it more likely meant "decomposes to the sesquisulphide, Mo2S3", rather than "oxidizes".
EDIT: Indeed, if it had meant "oxidizes in air", it would have said so. Therefore, I was wrong to assume it meant oxidation.
Decomposition to the sesquisulphide implies that the continuous flow cells would gradually get coated in sulphur on the inside, so they would have a limited useful lifetime. The question then is, how long would such cells last at any given temperature, and how easy would it be to restore them to the disulphide form?
