Fuel-cell cars cruise onto the market

Fuel-cell powered cars that emit only water vapor when driven have been in the works for decades, but progress seemed to keep stalling. Now, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the wait is over. Motorists can finally lease or buy hydrogen-powered, fuel-cell cars, but the road ahead for these vehicles still faces some bumps. 

C&EN Senior Correspondent Mitch Jacoby reports that the concept of fuel cells dates back to the 1800s. But the technology didn't achieve reliability until the 1960s and 1970s, when NASA used devices in the Gemini and Apollo missions. In some ways, fuel cells can be compared to their distant cousin, the battery. In both devices, electrodes extract electricity from . However, unlike batteries, fuel cells do not store the chemicals needed for the reactions: They draw oxygen in from outside air, and a fuel gets replenished at the pump. Getting fuel cells to work at a reasonable price point has been a slow process, but with growing manufacturing experience and steady improvements to efficiency, -cell cars entered the retail market in 2015.  

But how quickly the market will grow remains uncertain for a variety of reasons. Degradation and durability of components remain a concern. The relatively high cost keeps the cars out of reach for many consumers. Additionally, there are currently only 29 retail hydrogen filling stations in the U.S.—and they're all in California. But researchers are continuing to search for ways to lower costs and make improvements, betting that more and more private motorists will want to own one of these vehicles in the future.

The holdups stem from the fact that people insist they have to be -hydrogen- fuel cells which pretty much makes it a dead end because raw hydrogen is never going to be a practical fuel.

Fuel cells that operate with a wide variety of hydrocarbons do exist, but they get no love since they emit CO2. Cars are just not allowed to emit CO2 regardless of where it comes from - even if it's a sustainable synthetic or biofuel - so the fuel cell car is politically impossible.

Yet fuel cells operating on hydrocarbons would emit far less CO2 and virtually no other pollution even if they were running on fossil fuels, and they would make it possible to make a smooth cheap transition from fossil fuels to renewable energy by being compatible with both systems without the need for a new infrastructure. No hydrogen stations, no superchargers, the same pump can fuel your old V8 and your new electric fuel cell - it's just a question of where the fuel comes from.
