Then it would not be Kel-F as F&P claim in their paper. Kel-F's melting point is more like 200-215C, as I showed in the references in my prior post. F&P specifically say this: "furthermore the Kel-F supports of the electrodes at the base of the cells melt so that the local temperature must exceed 300ºC. "
You have a genius for missing the point. Suppose the temperature is 200 - 215 deg C, as you say. The point is, the plug melts in tests with Pd-D when there is excess heat, but it does not melt in control tests with Pt-H or Pd-H, when there is no excess heat. The exact temperature does not matter.
Your other comments also miss the point or they are mistaken.
By the way, information not found in this paper can be found in others, so perhaps you should misconstrue them as well.
