How much power does a Toyota Mirai fuel cell produce?
The Toyota Mirai, a hydrogen fuel cell electric vehicle, produces a maximum power output of 114 kilowatts (153 horsepower). This power is generated by the vehicle's fuel cell system, which converts hydrogen gas into electricity to drive the electric motor and charge the onboard battery.
Understanding the Toyota Mirai's Fuel Cell Power
The Toyota Mirai is powered by a hydrogen fuel cell, which is a type of electrochemical cell that converts the chemical energy of hydrogen and oxygen into electricity. Unlike traditional internal combustion engines that burn fuel, the Mirai's fuel cell system generates electricity through an electrochemical process, producing only water as a byproduct.
The Mirai's fuel cell stack is the core component that generates the electrical power. This stack contains numerous individual fuel cells, each producing a small amount of electricity. When combined, the fuel cell stack is able to produce up to 114 kilowatts of power, which is then used to drive the vehicle's electric motor and charge the onboard battery.
Factors Affecting Power Output
The Mirai's power output can be influenced by several factors, including:
- Hydrogen supply: The amount of hydrogen gas available to the fuel cell stack directly impacts the power output. More hydrogen allows for greater electricity generation.
- Operating temperature: The fuel cell performs best within a specific temperature range, typically around 70-80°C (158-176°F). Deviations from this optimal temperature can reduce power output.
- Load and driving conditions: The power demand placed on the fuel cell system, such as during acceleration or hill climbing, can cause fluctuations in the power output.
By managing these factors, Toyota engineers have been able to optimize the Mirai's fuel cell system to deliver a consistent and reliable power output for everyday driving.
Comparison to Other Vehicles
The Toyota Mirai's 114-kilowatt power output is comparable to other mid-size electric vehicles on the market. For example, the Nissan Leaf has a maximum power output of 110 kilowatts, while the Tesla Model 3 Long Range can produce up to 211 kilowatts.
However, it's important to note that power output is just one aspect of a vehicle's performance. Factors such as torque, acceleration, and overall efficiency also play a significant role in the driving experience.
How many kWh is a 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.

Can a hydrogen fuel cell power a home?
You can power your home using hydrogen fuel cell technology. Carbon-free and cost-effective. Clean, reliable power for your home.
How much DC output does a Toyota Mirai have?
The Toyota Mirai is equipped with two power supply units: a DC power source that can supply up to 9kW of power to a home, and an AC power source that can be used like a regular household outlet.
What is the MPG of a hydrogen fuel cell?
First, you need to know that hydrogen fuel isn't measured by gallons – it's measured by kilograms. A full tank for a Mirai is approximately five kilograms, and on a full tank, it gets about 66 MPGe (miles per gallon equivalent) of hydrogen gas.
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 power output of the Toyota Mirai fuel cell?
| FC stack | Name | Toyota FC Stack |
|---|---|---|
| Maximum output | 114 kW (155 DIN hp) | |
| Humidification system | Internal circulation (humidifier-less) | |
| Number of tanks | 2 | |
| High-pressure hydrogen tank | Nominal working pressure | 70 MPa (approx. 700 bar) |
What is the power output of a fuel cell?
The amount of power produced by a fuel cell depends on several factors, including fuel cell type, cell size, temperature at which it operates, and pressure at which the gases are supplied to the cell. A single fuel cell produces less than 1.16 volts—barely enough electricity for even the smallest applications.
How much power can a hydrogen fuel cell generate?
The membrane allows only protons to pass through and is called a proton exchange membrane, or PEM. In order to work properly the membrane must be kept moist. 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.
What limits the power output of a hydrogen engine?
Typically hydrogen engines are designed to use about twice as much air as theoretically required for complete combustion. At this air/fuel ratio, the formation of NO x is reduced to near zero. Unfortunately, this also reduces the power output to about half that of a similarly sized gasoline engine.
