Here is the quote.

We have developed an H2, O2, and H2O compatible all-quartz cell that has
been fabricated by a vendor.
I think it is likely that they could add a certain amount of lithium and argon and end up with a device that works extremely well. My guess is that Mills might know how to run it so that nuclear reactions don't happen very often and that most of the energy produced is from the hydrino transition. I think he may have to do that to protect his patent portfolio. In that case, the QX would have an advantage in that it would not need a continual source of hydrogen. I think over time Mills will have to admit that he can push his systems to produce LENR reactions as well.
