What is the fuel cell voltage in a Toyota Mirai?
The Toyota Mirai is a pioneering vehicle in the world of hydrogen fuel cell technology. As an owner of Kevin's Autos, I often get questions about the specifics of this innovative car, particularly regarding its fuel cell voltage. Understanding this aspect is crucial for anyone interested in the performance and efficiency of hydrogen-powered vehicles.
What is Fuel Cell Voltage?
Fuel cell voltage refers to the electrical potential generated by the fuel cell stack in a hydrogen-powered vehicle. In the case of the Toyota Mirai, this voltage is a key factor in determining the vehicle's overall efficiency and performance.
Fuel Cell Voltage in the Toyota Mirai
The Toyota Mirai's fuel cell stack operates at a nominal voltage of approximately 300 volts. This voltage is generated through a chemical reaction between hydrogen and oxygen, producing electricity that powers the electric motor and drives the vehicle.
Factors Affecting Fuel Cell Voltage
Several factors can influence the fuel cell voltage in a Toyota Mirai:
- Hydrogen Supply: The availability and pressure of hydrogen can affect the efficiency of the fuel cell.
- Temperature: Operating temperature can impact the reaction rates within the fuel cell.
- Load Demand: The voltage can vary based on the power demand from the electric motor.
- Age of the Fuel Cell: Over time, fuel cells may degrade, affecting their voltage output.
Understanding these factors can help owners maintain their vehicles and ensure optimal performance.
Conclusion
The Toyota Mirai represents a significant advancement in automotive technology, with its fuel cell voltage playing a crucial role in its operation. With a nominal voltage of around 300 volts, the Mirai showcases the potential of hydrogen as a clean energy source. As the automotive industry continues to evolve, staying informed about these specifications will help drivers make the most of their vehicles.

What is the voltage of a Toyota battery?
Your Toyota dealer offers free battery testing to determine its overall condition and health. A fully charged battery should register above 12.4 volts – anything lower may indicate weakness as it nears the end of its lifespan.
What is the ideal voltage of a fuel cell?
In an ideal (reversible) fuel cell, the cell voltage is independent of the current drawn, and would remain at 1.23 V. Practically, the ideal cell voltage of 1.23 V is not realized even at open circuit (zero current) due to the myriad irreversibilities that arise during fuel cell operation.
What is the cell voltage of hydrogen fuel cell?
A typical hydrogen fuel cell produces 0.5 V to 0.8 V per cell. To increase the voltage individual cells can be connected in series. This arrangement is called a fuel cell stack.

What is the voltage of the Mirai battery?
The Mirai has a 245V (1.6 kWh) sealed nickel-metal hydride (NiMH) traction rechargeable battery pack, similar to the one used in the Camry hybrid.
What is a disadvantage of hydrogen fuel cells?
Expensive to manufacture due the high cost of catalysts (platinum) Lack of infrastructure to support the distribution of hydrogen. A lot of the currently available fuel cell technology is in the prototype stage and not yet validated. Hydrogen is expensive to produce and not widely available.
What is the Toyota Mirai lawsuit?
Toyota wastes millions of dollars and pollutes the environment with its hydrogen-fueled Mirai vehicle, a new class action lawsuit alleges. A group of consumers from California claim Toyota “spins a web of lies” about the Mirai while exerting “unprecedented nefarious control over Californians.”
