I have read a report one experimental fuel cell unit installed in
Holland,
where it was mentioned that "At the point of shutdown, the unit was

sustaining a power generating efficiency of more than 46 percent,

a conventional combustion-based power plant that typically generates
electricity at efficiencies of 33 to 35 percent".
That is typical of an old station running coal or gas, built to 60's
standards. Noit a modern set.
The report was quite recent, like a couple of years old.
*shrug* maybe people aren't too bothered about efficiency and still
build cheap gas powered sets.
*more shrug* Maybe 60% is reached in the occasional "flagship" power
station. I think it is exceptional.
