Was trying to remember their name.
I think the Ceramic Fuel cell and the panasonic product referred to above are what are known as Solid Oxide Fuel Cell. Something that I looked a bit into when invested in CLQ due to their use of scandium. "These cells take a variety of input fuels, including liquid or gaseous
hydrocarbons[1] produced from biological sources, to produce
electricity at or near the site where it will be used." wikki
Currently being used by a large number of US companies. Bloom are probably the biggest manufacturer in the states. Here is a link to their site and the names of corporates using same. Even powering some data centres.

Still some cost issues in the manufacture which hopefully cheap Sc and scale of demand will affect.
