Question

What's the lastest on hydrogen fuel cells?

Answer 1

A real fuel cell takes hydrogen and turns it into electricity.  They're troublesome, expensive, and there's no convenient place to mine hydrogen.  The bogus 'fuel cells' that Water 4 gas and the rest of them advertise takes water and, with lots of current from the battery, electrolyzes the water into insignificant amounts of hydrogen and oxygen gas.  These are supposed to vastly increase the mileage of your gasoline car engine, which they don't.  

There have been no particular improvements in fuel cells in several years.  

Answer 2

You must read the articles below  in particular the second from the last one. The last one has  a site with  video lectures January 18, 2008 and January 25, 2008 on fuel cells

The Caltech Center for Sustainable Energy Research (CCSER) has as its ambitious goal to transform the industrialized world from one powered by fossil fuels to one that is powered by sunlight. The vast resource potential of solar energy—more energy from sunlight strikes the Earth in one hour than all of the fossil energy consumed on the planet in one year—motivates the Center's work on the science and engineering innovations required to harvest the enormous potential of solar energy.

Fuel Cells

Chemical fuels enable energy storage, but require methods for clean and efficient conversion to electricity on demand. Therefore, the third focus of CCSER is on fuel cells, where again, a key objective is to develop alternatives to platinum as a catalyst for conversion of renewably generated hydrogen or hydrocarbon fuels. This is made possible through the discovery by CCSER researchers of a new class of fuel-cell electrolytes, solid acids, that can operate at temperatures higher than polymer electrolyte membrane fuel cells, but far lower than solid oxide fuel cells.

Answer 3

true fuel cells are very expensive.  A car would cost over $100,000 using them. Anad as pointed out, H2 is hard to find or you buy a lot of natural gas put it in piece of equipment and get H2 out (100 units natural gas get 50 units of H2) making the H2 very expensive AND, you make pollution when you make the H2, so it is NOT CLEAN FUEL!!!!
