EVS23: Fuel Cell or Fool-Sell, Hydrogen Hype Tape 4
Fuel cells require Hydrogen, which has a much lower energy density than CNG at low pressures. Hydrogen is perhaps the most difficult gas to deal with, as it infiltrates most metals leading to the “embrittement” problem. But that’s not the worst problem for fuel cells. You have to make the Hydrogen, which takes more energy than you get out of it. The fuel cell, in practice, is only about twice as efficient as an Internal Combustion (“IC”) engine, so it takes a lot more energy to run a fool sell car than an EV. But even worse, fuel cells work in space, because the gov’t uses our money to send pure Oxygen as well as Hydrogen but fool sell cars use ambient Oxygen, which is mixed with contaminants that limit the life of the fuel cell stack to no more than about 3 years. Then there’s cost, and other issues.

i think that was the wrong person to ask questions. But all is good
1 million dollar fuel cell car?
fuel cell technology is dead ITS WAY TOO EXPENSIVE TO PRODUCE FOR THE LIKES OF THE ORDINARY GUY WHO WORKS IN THE FACTORY
WE NEED CHEAP LOW COST VEHICLES
I talked to Daimler at the car exhibition in Frankfurt in 2007 about H2 Fuelcells, and thy told me they are doing Datamining. That means that the fuelcells sometimes fails and they don’t know why. I’ve seen some of the cars at a research-Centre in Ulm, looked very much like any other car, because the A-Class is made to be an electric car, so all the components can be integrated in the bottom of the car, but they should use Nimh, LiFe or ZEBRA.
Fuelcells burn more money than Hydrogen
.
HHO ? no, just H2 in gas bottles. Why?
You need H2 for those fuel cells… they dont accept other gasses. They will degrade even faster. They degrade because they dont get pure oxygen out of the air. There is a little fan on the fuel cell that circulates the air.
Do you have any HHO Generators in those schools – young fella. There is a difference you know. You won’t learn it book.
This video shows what fuel cell really is: It’s crap.
Nobody gets told it degrade’s ( they only tell battery’s degrade.. but fuel cell? they dont want to tell it .. )
And the power output is poor. And you stop and start a car ALOT. And thats bad for a fuel cell either.
Put the fuel cell investigation money in battery investigation.. Would be alot better!
He said 4000 hours to 9000 hours? thats like 5-10 years if you drive 2 hours a day. ( to work )
As always.. we want NUMBERS!
Overpriced education?? you didnt even go school right? you don’t know we do research to!! We don’t get told at us like Here this is it.. and its like this. No we have to investigate ourselfs! And we have fuel cells at school few of them. And it’s a big LIE!.. ill tell ya!
Is it plausible that this would be cheaper if it were mass produced? Daahhhh!
I love it hydrogen car I must be dremming .
make more cars please .oil companies greedy bastad watch this video is free.
“You didn’t say anything at all, you sound like a politician.”
XD
That would be a “regenerative” fuel cell, that hydrolyzes the water it produces back to constituent O2 and H2 gases, recompresses them (possibly in a lower-pressure separate tank) when BRAKING. But overall, regen braking only recovers a FRACTION of the energy it took to get the vehicle moving in the first place.
So here’s a question…If the electrolysis process were performed on-board and the component hydrogen/oxygen gases were sent directly to the fuel cell, would this alleviate the filtering problem?
Ok to start there are all ready post card cars using hidrogen as energey and it last for long time i drive one so this is better than using gas if that to bad of power recorce and why dont you use a nuclear power plant in your car?? You ass hole to the end punk mother fucker.
You didn’t say anything at all, you sound like a politician. Fuel Cell tech is expensive, inefficient, the fuel is expensive, the whole ecosystem has to be set up, it just makes no sense. EVs are the way to go, EVs and EREVs. I’ll forgive GM for the EV1 if the Volt works out, hopefully it will, the rest of the industry will follow suit.
Hydrogen technology is coming fast; not from the scientists; not from the highly educated; but from we the people; the ones with the “Common” sense. We remember the Past; We live in the Present; and we make the Hydrogen Future – TODAY.
No future for a hydrogen economy? Pure Physics? Put away that overpriced education. I generate hydrogen & oxygen, while I drive, using water and the left over power of my alternator; achieving as much as 66 miles on a quart of gasoline. Others have achieved more; much more.
PEMFCs use a platinum catalyst, which is very expensive.
$7,000/kW. It is true that the costs of PEMFC might conceivably be reduced over time due to technology improvements (although no real cost reduction has been achieved over the past decade despite several billion dollars in research investment). Moreover, if somehow the vehicles ever went into mass production, increased demand would drive the price of the platinum they contain, and thus the overall system cost, through the roof.
Whatever the weight is it. The FCX PEMFC is one heavy block of $700,000 worth of platinum catalysts that only lasts for 3 years.
we need a degradation graph in practical car use. looking at this limited spec sheet: w w w. ballard. com/files/pdf/Spec_Sheets/SPC5101375_-_Mark1030. pdf
it says it can only run above freezing. that’s a complication as well. a curious detail is the low power density though. little over 1kW for a 20kg package. 60kW would weigh a ton. Honda claims the FCX clarity has 100kW power. I wonder what that stack weighs
FC seminar Oct. 17 expects fork lift PEM life of 3-5 years. I should have forced Ballard to disgorge this info.

I was baiting them with questions to which I already knew the answers: for example, the one which elicited their claim to filter out HxCx. I should have challenged the “4000 hours” to ask “how many years”?
After watching the YouTube “Energy and Climate: Challenges and Solutions” I can confidently say that Hydrogen does not stand a chance in working. Hydrogen is really not that good of a fuel for transportation. Simply put, there is more hydrogen in a gallon of gasoline than there is in a gallon of liquid hydrogen.
You’re right. The “4,000 to 10,000″ hours somehow has to translate to 3 years of life, which comes from a separate source. This was just sloppy on my part. I should have asked “how long?” and forced them to clarify that the stack only lasts 2 to 3 years.
Also watch this YouTube: UCSD Division of Physical Sciences “Energy and Climate: Challenges and Solutions.” It weighs EVs versus H2 FC cars. Joseph J. Romm’s arguments against the FC is much much simpler than oilfree’s. In that YouTube they say that viable FC’s might be 5 to 50 years out.
