These are not teething pains of a new technology.

The first fuel cell was built in 1840. Fuel cells were put on Gemini rockets starting in 1962. The first fuel cell forklift was manufactured in 1965.

Compressor failures are the biggest issue with compressed natural gas fleets, and that's lower pressure and much bigger molecules.

Fuel cells require pure, dry, temperature controlled air and pure hydrogen or they foul and fail.

The maintenance and dispensing issues aren't going away.
