A phase change -- from meaning from gas to liquid, or liquid to solid -- can change the rate of cooling but it cannot make it anything other than a monotonic decrease as far as I know. Perhaps you should cite a textbook on this. We are talking about kilowatt levels of heat lasting for hours. In the electrochemical systems, changes in the lattice loading phase change the gas release rate and can make a recombination increase or decrease. This would increase the heat. You can see this happen quite clearly with the naked eye. The number of bubbles on a Pd the cathode surface dramatically increases as one phase ends and another begins. This is a fuel delivery system. Rossi's cell is not electrochemical, obviously. I do not think there is any mechanism that would free up hydrogen gas, and in any case the hydrogen is not burning (recombing) because it is not escaping from the cell (degassing) and because there is no oxygen. The pressure is the same at the end as at the beginning. - Jed
