I have seen at least two questions regarding the possibility of water vapor in the LENR apparatus previously described. There should be very little since the hydrogen generator I'm using has an in-line dehydrator cartridge and guarantees < 1 ppm water vapor in the hydrogen as long as the dehydrator cartridge is not exhausted. For details see Parker Balston hydrogen generators.
Before adding hydrogen the cell is heated to 350C under continuous vacuum pumping, so there should not be much residual water. If there is any it will quickly react with the Li producing LiOH.
