The Toyota Mirai’s hydrogen tank is a marvel of engineering, with a 5.6 kg capacity operating at 70 MPa. This innovative design enables the vehicle to achieve an estimated range of 500 miles on a single refill, making it an attractive option for environmentally conscious drivers.
Description of the Toyota Mirai’s Fuel Cell System Technology
The Toyota Mirai is a hydrogen fuel cell electric vehicle (FCEV) that produces electricity from hydrogen and oxygen to power the vehicle. This is a game-changer in the automotive industry, as it offers a zero-emission alternative to traditional internal combustion engines.
Fundamental Process of Electrolysis
The Toyota Mirai’s fuel cell system relies on the fundamental process of electrolysis to produce hydrogen. Electrolysis is the chemical reaction that occurs when an electric current is passed through a conductive substance, such as water, causing it to split into its constituent elements – in this case, hydrogen and oxygen. This process is reversible, meaning that hydrogen and oxygen can be combined to produce electricity and water through a process known as fuel cell reaction.
H2 + O2 → H2O + electricity
This process is the cornerstone of the Toyota Mirai’s fuel cell system. The hydrogen produced through electrolysis is stored in the vehicle’s hydrogen tank and is used to power the fuel cell, which generates electricity to propel the vehicle.
Critical Differences between Hydrogen Storage and Conventional Vehicles
The Toyota Mirai’s hydrogen fuel cell system presents several critical differences compared to conventional internal combustion engine vehicles. One of the most notable is the method of storing hydrogen. Conventional vehicles use gasoline or diesel fuel, which is relatively easy to store and transport. Hydrogen, on the other hand, requires high-pressure storage due to its low energy density. The Toyota Mirai stores hydrogen in a high-pressure tank at a pressure of 10.0 MPa (1450 psi). This is in contrast to conventional vehicles, which can store gasoline or diesel fuel at relatively low pressures. Another critical difference is the infrastructure required to support hydrogen fuel cell vehicles. Hydrogen fueling stations are still relatively rare, making it difficult for owners of FCEVs to find places to refuel.
Advantages and Challenges
The Toyota Mirai’s fuel cell system offers several advantages over conventional vehicles, including zero-emission operation, quiet and smooth ride, and improved efficiency. However, there are also several challenges associated with hydrogen fuel cell vehicles, including the high cost of hydrogen production and distribution, the limited infrastructure for hydrogen fueling, and the risk of hydrogen embrittlement in high-strength materials.
The Toyota Mirai’s fuel cell system is a complex and sophisticated technology that offers several advantages over conventional vehicles. While there are several challenges associated with hydrogen fuel cell vehicles, the benefits are clear. As the automotive industry continues to evolve, we can expect to see more FCEVs on the road, and with the development of a more extensive hydrogen infrastructure, the benefits of this technology will become increasingly clear.
Hydrogen Tank Capacity Analysis
The Toyota Mirai’s hydrogen tank capacity is a crucial aspect of its fuel cell system technology. Its ability to store and utilize hydrogen efficiently directly impacts the vehicle’s range and overall performance.
Hydrogen Tank Pressure Measurment in MPA
Hydrogen tank pressure is typically measured in MegaPascals (MPa), which is a unit of pressure. In the context of the Toyota Mirai, the hydrogen tank operates under a pressure of around 35-40 MPa. This high pressure is necessary to store sufficient hydrogen for the fuel cell system to generate electricity. The relation between tank pressure and fuel efficiency is indirect, as higher pressures can allow for more efficient storage of hydrogen. However, excessive pressure can lead to decreased efficiency due to increased energy requirements for compression and storage.
- High pressure in the hydrogen tank allows for increased storage capacity, which can translate to a longer driving range for the Toyota Mirai.
- On the other hand, excessive pressure can lead to a decrease in fuel efficiency due to the increased energy required for compression and storage.
Advantages of High-Pressure Hydrogen Tanks
High-pressure hydrogen tanks offer several advantages for modern fuel cell vehicles like the Toyota Mirai:
- Increased storage capacity, allowing for longer driving ranges and reduced refueling times.
- Higher energy density, enabling more efficient use of hydrogen.
Limitations of High-Pressure Hydrogen Tanks
While high-pressure hydrogen tanks have numerous advantages, they also have some limitations:
- Higher pressure increases the risk of leaks, which can compromise the safety and efficiency of the system.
- High-pressure tanks require more robust materials and manufacturing processes, leading to increased production costs.
- Hydrogen storage at high pressure can lead to the formation of hydrogen bubbles, which can affect fuel efficiency.
Hydrogen storage at high pressures has been identified as a major factor in determining the performance and efficiency of fuel cell vehicles.

Pressure Relief Valves
The Toyota Mirai’s hydrogen tank design includes pressure relief valves to release excess pressure in the event of an increase in tank pressure beyond the set limit. This is achieved through a specially designed check valve that opens when the pressure in the tank reaches the predetermined threshold. Once activated, the pressure relief valve allows gas to escape, maintaining tank pressure within the prescribed limits. This safety feature is critical for preventing the tank from bursting due to increased pressure.
Double-Walled Tank Design
Toyota has implemented a double-walled tank design to minimize the risk of hydrogen leaks and ensure additional protection against damage or malfunction. The fuel cell vehicle’s hydrogen storage system incorporates a secondary, leak-tight tank surrounding the primary tank. This setup isolates the fuel in the primary tank, reducing the risk of accidental hydrogen leakage. Furthermore, the double-walled design aids in the early detection of potential issues by monitoring the space between the primary and secondary tanks. This allows for timely maintenance and prevents potential problems from escalating into more serious malfunctions.
