What are Fuel Cell Electric Vehicles? Will They Replace BEVs?

Get Electric Vehicle

Fuel Cell Electric Vehicles (FCEV) are similar to BEVs in that they have an electric-only powertrain, but they store energy differently. FCEVs store hydrogen gas in a tank rather than charging a battery. The fuel cell’s electricity then powers an electric motor, which drives the vehicle like a BEV.

New PNNL zinc-polyiodide redox flow battery offers 2x energy density of next-best system; potential for mobile applications

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have developed a new zinc-polyiodide redox flow battery offering more than two times the energy density of the next-best flow battery used to store renewable energy and support the power grid. When power is needed, the two liquids are pumped into the central stack.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). Flow batteries are safe, stable, long-lasting, and easily refilled, qualities that suit them well for balancing the grid, providing uninterrupted power, and backing up sources of electricity.

OSU team develops new aqueous lithium-iodine solar flow battery; 20% energy savings over Li-I batteries

Green Car Congress

During the photo-assisted charging process, I − ions are photo-electrochemically oxidized to I 3 − , harvesting solar energy and storing it as chemical energy. Both the CE and PE are in contact with the flowing catholyte, which is stored in a reservoir connected to the catholyte chamber and pumped through the device using a peristaltic pump.

Opinion: Debunking the mythsWhy fuel cell electric vehicles (FCEVs) are viable for the mass market

Green Car Congress

This renewable production capacity is increasingly important to ensure the existing power grid can accept more renewable sources. Myth #2: Hydrogen gas is dangerous to store and use. Of course, this also has the merit of producing so-called “green hydrogen”. Myth #5: FCEVs don’t have enough energy for long journeys.

As one point of comparison, customers bought 54,451 Nissan LEAFs EVs in fiscal year 2017—a 15% increase from 47,423 a year earlier. The power electronics are effectively a link that controls the flow of high-voltage energy between the motor and the battery. model itself.
