Fuel Cells Rush In
Last Updated (Tuesday, 26 January 2010 10:31) Written by Raymond Nakamura
A silver car covered in bubbles passed me on the Burrard Street bridge the other day. On second glance, I realized the bubbles were decals of water molecules. It was a fuel cell car. I thought they were still the stuff of science fiction, but apparently not.
On the Road
I found out that fuel cell cars are here for the Vancouver Olympics. They are using hydrogen to produce electricity to run the motor. Apparently, other fuel cell cars were tested here before. Ballard, a leader in fuel cell technology based in Burnaby, sold off its car projects to focus on other applications as back-up generators and so on.
What's Old is New Again
The idea for fuel cells has been around for over 150 years. They proved themselves in the space program, providing both electricity and water from hydrogen and oxygen.
More than One Way to Skin a Cation
Various kinds fuel cells are being developed now, based on different fuels and ways of extracting electricity from them. The basic idea is that a catalyst takes the electrons from the hydrogen atoms to produce electricity and hooks up the hydrogen ions with oxygen to make water. This part is clean and quiet. The car I saw had four slots in the back with little wisps of what I guess were water droplets coming out.

Bum Rap
Some people associate hydrogen with the Hindenberg blowing up way back when. This rep is not helped by the big explosion of the fuel cells running the desert hotel in the James Bond movie, a Quantum of Solace. Never mind that. Though they do make for louder balloon demos.
Bright Idea
In practise, a greater concern is the distribution of hydrogen. Although hydrogen is the most abundant element in the universe, it tends to be connected with other elements. So you need to use energy to get it on its own. Solar power is clean but not always available. Using the sun to create energy to produce hydrogen can be a convenient way to generate electricity on demand.
Road Blocks
Besides hydrogen distribution, other challenges for fuel cells is their cost, and ability to function in cold weather.
So keep your eyes out for fuel cell cars — you might not hear them.
And if you've driven a fuel cell car. please share what it was like.

I know what you mean about the attention deficit situation.
Thanks for the offer!
If you're serious about letting me try one out, please contact
webmaster@scien ceworld.ca
for my info.
The safety issue of biggest concern in my opinion is people being distracted as they drive and walk. That's why we're seeing bans on using mobiles while driving and why we're hearing about the increase in car accidents involving pedestrians. Just last night, there was another story on the news about this very issue. People aren't paying attention. On foot, or behind the wheel.
Are you based in Vancouver? If so, I'd love to get you into a fuel cell car for a test drive, and a refuel. Let me know if you're interested and we'll try to sort something out. :-)
Did you know that Vancouver also has fuel cell buses? They'll be running up to Whistler during the Olympics.
