Default Hydrogen Fuel Cells for RC Cars

I just came across this and thought I'd share.

I just saw this too, they claim 50mph for up to 45 minutes of runtime! I bet it costs an arm and a leg though

I saw information on these a couple of years ago, but the rub then was that they couldn't get the cell to output enough power to drive the motor at a high enough RPM to make it appeal to the RC community. The kits are good and if you ever wanted to tinker with power cell technology they are worth the $$. I'm not sure if they have overcome the power issue, but if they have it would be worth the look. The other issue is heat, with more power from a fuel cell comes more heat. As you can see from the pictures, there are two prety heavy duity fans on that thing.

Just thought I would do some quick research. As a reference point the Novak Ballistic 10.5 outputs 235W over 6 minutes. That is 2350Wh. These guys use something called a HydroSTIK to store their H2 in a solid state. It's kind of like a battery. Each stick stores 15Wh of energy. Doing the math, you would need 157 of these guys to power a 10.5 for 6 minutes. Granted that is the 10.5 at full power, but still.

I currently work in the rc car industry and we have tried many different things to do for powering the car and storing energy. Hydrogen, while great, does not transmit near enough energy using current processes for energy capture. We always keep coming back to the basic battery pack that plugs into the wall and a good, efficient motor. It's the same problem as the large scale cars with internal combustion engines and gasoline. They have been around for quite some time and allow the most bang for the buck.
Currently, hydrogen powered rc cars are a pipe dream because coal/oil powered electricity from an outlet is too damn cheap to allow this to really catch on. Until the price improves, the cars are fast enough, and until there is an obvious advantage that will not cause the enthusiast to go out of their way to use it; this thing is just a concept car of the rc world.
If I've learned one thing since I've been in my career, it's not always necessary to reinvent the wheel. The customer is used to something and expects it to be that way. I truely believe that's why the brushless movement caught on. The racing wasn't all that different, but it improved performance and freed up time that would be spend motor tinkering to work on other aspects of the rc car. This hydrogen car is sweet, but it needs to be lighter, faster, and eventually price competitive. Unfortunately, it just isn't any of those things. I don't want to be negative because this is a great idea, but it's a bit of a letdown for an enthusiast.

We mainly sell inexpensive RTR's at WalMart, Target, and ToysRUs. I work for New Bright RC. It's an el cheapo manufacturer but we do tons of great experimentation. The big box retailers are very hesitant to do "creative" projects so we can only go so far into the hobby realm. At least we got the Chinese to start making lexan bodies. lol

Questions?? why so serious

this sounds more like a joke ,your gonna have to pay to refill a hydrogen cell so you can run an electric yeah the cost of running this car is double when compared to a standard lipo set up of today just a waste of money but who knows what the future will be in a few years

Exactly. Not always, but most times, it comes down to cost. I can't tell you how many bad ass ideas we have that DON't get made due to cost. The other concern is efficiency. This just isnt an efficient business model in general.
