$this->bbcode_second_pass_quote('', 'e')ven electric motors wear out so no problem for the auto companies there..
There are people who have been using the same electric motor to power their cars since the 60s. They might wear out, somewhere between 500,000 and 1 million miles!
Fuel cells are mostly a shell game to placate a public wary about continued oil reliance. The auto industry needs to make the public think a solution is in the works, so that an angry public won't demand that less profitable alternatives that are currently viable take the place of the internal combustion engine. Electric cars are perfectly viable, far cheaper per mile to run factoring battery costs, than a gas car, but their virtue of being cheap means less money flows from the consumer to the company.
electric cars, by their design, are perfect for a closed system, zero growth economy. Therefore, the 'capitalists' stay as far away from them as possible. (I put capitalists in quotes because more or less these companies are as commie as they come, raking in government handouts to line their pockets) But if we are to keep something close to our current living standard and still have some cars for the middle class in the future(They should be an option, not a necessity), the electric car will be a significant factor in allowing this. If the auto industry refuses to bring it out and is never forced into it either by angry consumers or mandate, the car may be history.
A fuel cell car in mass production would cost 5-6 times more than a typical car to produce. Toyota hopes to get the cost of a mass produced fuel cell car down to $50,000 in 2005 dollars 10 years from now. Their goal may not be met. The fuel cell stack is expensive, per kW of peak power in mass production fuel cells would go for over $500/kW. Or $20,000+ for the fuel cell stack alone to give a car 54 horsepower.
The hydrogen storage tanks are far heavier than any battery. Fuel cell cars that are compact like the Honda FCX weigh in at near 4,000 pounds. Midsize cars using fuel cells will be even heavier. Likewise, battery technology has progressed to where a pack of lithium ion batteries to give a battery electric car 200 miles range plus the electric motor will weigh less than a comparable internal combustion engine.
Some magazines claim these hydrogen fuel cell cars have 200 miles range. That's the case, with very gentle acceleration in perfect weather. Most fuel cell cars have ranges hovering around 40-60 miles, which is what an inexpensive pack of lead acid batteries can do for an EV. If you want to get more than 150 miles range in a fuel cell car, there exists considerable waste in pressurizing the hydrogen to get enough into the tankEven to pressurize the hydrogen into a fuel cell car's tank takes 20+ minutes. Fast charge stations for battery electric cars could charge your battery pack in a comparable time frame.
Well to wheels, a battery electric car is about 2-3 times more energy efficient than a comparable gas-powered car(not a hybrid), BUT a hydrogen fuel cell car well to wheels is about as efficient as a comparable gas car.
Fuel cell cars are greenwashing. A shell game. Nothing more. They exist to make the public forget about the fact that off the shelf components can now make a cost-competitive EV with an internal combustion car, if the EV were to be mass produced.
