How long do hydrogen fuel cells last?

Hydrogen fuel cell cars now average between 312 and 380 miles of range, according to the EPA. When it comes to longevity, think of a hydrogen-powered fuel cell electric car the same way you would a conventional gasoline or diesel car. Therefore, the fuel cell of a Toyota Mirai is designed to last the life of the car, with the same quality, durability and reliability as any other Toyota. What is striking is that the exact same terms of discussion could have been used a century ago.

You must replace fuel cells and hydrogen with the combustion engine and oil. In 1917, the battery was already 4 or more times more efficient than the combustion engine. Even so, gasoline and combustion engines completely prevail, essentially because they were more practical (fast refueling, greater autonomy and, in the long run, it was easier to create an oil refueling infrastructure). Answer: Simply wrong, FC systems are known for their reliability and robustness.

The ONLY thing electric cars perform better at than hydrogen cars is their efficiency, but the fuel cell is still better than the most efficient ICE (38% of Toyota) currently developed. The company began as a natural gas truck company, then moved to hydrogen fuel cell vehicles, then to a mixture of fuel cell hydrogen and battery electricity, and today the company's first truck to hit the market is a truck with an electric battery, years before its FCEV programs. Technical and economic advances in battery and fast charging technologies could soon make fuel-cell electric vehicles, which run on hydrogen, unnecessary in road transport. Most have opted for battery-powered electric vehicles (BEV), but some car manufacturers have insisted on trying to make hydrogen fuel cell powertrains work.

I just saw a guy fill his fuel cell car with hydrogen, and it didn't seem any harder than filling it with gas, besides there was no smoke. Assuming that a large quantity of hydrogen is produced from cheap and variable energy for such purposes, the additional cost of supplying hydrogen for transport may be reasonable. There is no doubt that hydrogen is THE fuel for Earth and space, BUT the answer is technology to convert water into hydrogen in place of the device or vehicle WITHOUT having to transport or channel hydrogen to the device or vehicle. This criticism of fuel cell cars is based mainly on two arguments (the lower energy efficiency of the FCEV compared to my simple and logical provisional suggestion (pending the development of fuel cells in cars and local service stations) would be to replace petroleum-powered or nuclear power plants with hydrogen, achieve the short-term ecological objective and concentrate complicated driving deficiencies in fewer geographical areas where they can be safely controlled.

I'm not against fuel cell technology and I also support it, but electric cars that use batteries to store energy are a much better technology right now and probably for the next 30 years or more. However, this seems highly unlikely compared to company announcements that the earliest start date for the production of commercial series fuel cell electric trucks will be in 2027. Not to mention that fuel cell cars have tons of complex parts, plus a tank of bombs and less passenger space and storage space. .
