A presentation at a cold fusion conference isn't exactly publishing, but let's look at the claimed results.
On pages 5 and 6 we see that they didn't get excess power until after 64 days, and then it was only one watt. I can see why people consider such trivial claimed power production to be intangible. After several million dollars of funding the result is pathetic.
I suggest you look at page 9. A total power output of ~300 MEGAJOULES (~83KWH) from a piece of palladium 100 mm long and 2 mm in diameter.
As to "...they didn't get excess power until after 64 days"...", this work is from 1996. Since that time, other researchers have fixed the problem of a long "lead-in" time. Several researchers have devised means of generating excess power at or shortly after startup.
