Comments on claims of excess enthalpy by Fleischmann and Pons using simple cells made to boil

Fleischmann and Pons have claimed to have performed a ''simple'' experiment and to have observed excess enthalpies larger than 1 kW/cm3 of palladium. It is shown that in fact the system they use is exceedingly complicated, is under-instrumented and that they have ignored several important factors so that it is unclear whether or not they have observed any excess heat.
