How long will a hydrogen fuel cell last?

H2 fuel cells currently in production have a life expectancy of from 5,000 to 10,000 hours. If we apply that to an average driving speed of 45 mph (a combination of in-town on highway driving), we should expect to get 225,000 to 450,000 miles.

That is comparable to the lifetime (between rebuilds) of modern internal combustion engines (ICEs), depending on various factors.

Fuel cell vehicles operate at much higher efficiency levels than ICEs (approximately 3X). That means the value of Hydrogen and gasoline are equivalent when the price per kg of H2 is about 3 times the price per gallon of gasoline.

There are additional benefits as well. If the H2 is produced by splitting water with energy obtained from renewable sources, such as wind turbines, then the entire fuel cycle is sustainable indefinitely, with no production of CO2.
