On February 14, Toyota Motor Corporation announced the development of its new third-generation fuel cell (FC) system.
As part of its commitment to achieving carbon neutrality, Toyota has identified hydrogen as a key energy source and has been collaborating with partners across various industries. Recognizing the need for further advancements in fuel cell technology, Toyota has developed this new system to accelerate efforts toward a hydrogen-powered society.
Regarding the newly developed third-generation FC system, the company stated:
"The new system has achieved durability comparable to that of a diesel engine, making it particularly well-suited for the commercial sector, which will drive the adoption of hydrogen energy."
Additionally, Toyota has focused on enhancing multiple performance aspects, including fuel efficiency, while also reducing costs. The company plans to expand the application of this system beyond passenger cars to large commercial vehicles. The new fuel cell system is set to enter markets in Japan, Europe, North America, and China starting in 2026.
Toyota’s Commitment to Hydrogen and Fuel Cell Technology
Fuel cell technology has evolved significantly, with various types of fuel cells emerging to meet different energy demands.
Among them, Proton Exchange Membrane (PEM) fuel cells stand out for their efficiency and suitability for automotive applications, such as Toyota's third-generation fuel cell system.
These fuel cells use hydrogen and oxygen to generate electricity, emitting only water as a byproduct. Another innovative approach is the Microbial Fuel Cell (MFC), which utilizes microorganisms to break down organic matter and produce electricity, showing potential in wastewater treatment and sustainable energy production.
While PEM fuel cells are optimized for high-performance applications like fuel cell batteries in vehicles, MFCs represent an alternative bio-electrochemical energy source that could complement future clean energy solutions.
Debut at H2 & FC EXPO
The third-generation FC system will be publicly unveiled for the first time at the H2 & FC EXPO (Hydrogen and Fuel Cell Exhibition), taking place on:
Venue: Tokyo Big Sight, Koto-ku, Tokyo
Main Exhibits: Third-generation FC system (first public release)
Water electrolysis stack
Portable hydrogen cartridges
Special Presentation
A special presentation will be held at Toyota’s booth, titled:
"Toyota’s Initiatives Towards the Realization of a Hydrogen Society" (tentative title),
delivered by Hydrogen Factory President Mitsumasa Yamagata on February 19, from 14:00 to 14:20.
Overview of the Third-Generation FC System
Toyota introduced its first fuel cell electric vehicle (FCEV), the MIRAI, in 2014. Since then, the company has sold approximately 28,000 units across more than 30 countries and regions. Additionally, since 2019, Toyota has supplied over 2,700 FC systems to more than 100 users worldwide for applications in buses, trains, stationary generators, and other sectors.
In Japan, Toyota is actively collaborating with partners—particularly in Tokyo and Fukushima Prefecture—to implement its FC systems in the commercial sector.
Key Features of the Third-Generation FC System
Enhanced Durability
Equivalent durability to diesel engines, with maintenance-free operation
1.2x improvement in fuel efficiency
Expanded Applications
The third-generation FC system is designed for various applications, including:
General-purpose use – Suitable for stationary generators, railways, ships, and other applications
Large commercial vehicles – Compact design with high output and durability comparable to diesel engines, making it easier to integrate into different types of commercial vehicles
Toyota continues to advance hydrogen fuel cell technology, aiming to create a sustainable and hydrogen-powered future.
