That is great! I have been thinking for a long time that catalytic converts should be used in cold fusion. They are engineered to be robust, and to expose all of the catalytic metal to the gas. Off the shelf hydrogen filters have been used to good effect. Hydrogen filter palladium is engineered to be robust. In this case, to withstand high loading without cracking. If the gain is really from LENR then it makes more sense to use hydrogen from a tank - there is no need for electrolysis and the risk of explosion from HHO. And no need for a very expensive hydrogen filter. And no need for oxygen either. Of course, many of the proponents think that HHO as a mixed gas is more potent than is the same amount of H2 from a tank, but that is not proved. A meaningful experiment to test for LENR would be an Arata - Cravens type of unpowered experiment with low pressure hydrogen filing a sealed catalytic converter (flushed of air so no combustion). Do you get a small temperature gain with no power input? Based on Cravens demo, there could be a significant thermal gain given the very large amount of catalyst in contact with H2.
