Honda announces next-generation fuel cell module, reducing costs by half and tripling power density

[PCauto] At the 23rd International Hydrogen and Fuel Cell Expo (H2 & FC EXPO) held at the Tokyo International Exhibition Center, Honda unveiled its next-generation fuel cell module alongside detailed specifications for its fuel cell generator.

Mass production of Honda’s fuel cell module is slated for 2027, whereas the fuel cell generator is set to enter production in 2026.

The unveiled fuel cell module represents the culmination of Honda’s independent research and development and is destined to replace the current model, which was jointly developed with GM (General Motors). With a rated output of 150 kW, it offers significant advantages over its predecessor.

Production costs have been halved, rendering hydrogen fuel cell technology more competitive in commercial applications and potentially lowering product prices for a broader range of consumers. Furthermore, durability has been enhanced over twofold, ensuring that devices and vehicles incorporating this module will benefit from extended service life, reduced maintenance and replacement expenses, and more consistent, reliable energy support.

Notably, by boosting the volumetric power density by more than three times, the module has been substantially miniaturized. Since volumetric power density quantifies the electrical energy output per unit volume, a higher density translates to greater power output in a compact space. This advancement enhances layout flexibility within the automotive sector—allowing designers greater freedom in vehicle interior planning and improved space utilization—while also accommodating varied spatial requirements in other application fields.

In pursuit of its ambitious goal of achieving carbon neutrality for all products and business activities by 2050, Honda has delineated four pivotal sectors for its fuel cell system applications: FCEV (fuel cell electric vehicles), commercial vehicles, stationary generators, and construction machinery. The introduction of this fuel cell module marks a critical milestone in broadening Honda’s hydrogen energy portfolio. By extending both the application spectrum and market reach of its systems, the company is ardently progressing towards a sustainable, energy-driven future.

Honda has long been at the forefront of hydrogen energy exploration, emerging as one of the early pioneers to recognize hydrogen’s potential in realizing a carbon-neutral society. For over three decades, the company has been deeply engaged in the research and development of hydrogen energy technologies and FCEVs. In addition to the fuel cell module, Honda showcased its fuel cell generator—set for mass production in 2026—which functions as a stationary energy storage system engineered to supply hydrogen-derived clean electricity to large facilities such as factories and offices. This generator smartly incorporates the fuel cell technology featured in the Honda CR-V e:FCEV and, by optimizing its cooling system design and internal layout, achieves a compact footprint adaptable to diverse installation environments. Moreover, with an emphasis on rapid response, the generator is designed to commence power supply within 10 seconds of startup, ensuring a highly reliable backup energy source.

The principal advantage of Honda’s newly unveiled fuel cell module and fuel cell generator lies in the dramatic reduction of production costs—a pivotal development in transitioning from laboratory research to market commercialization. With plans to begin mass production of the fuel cell generator in 2026 and the fuel cell module in 2027, Honda is poised to introduce groundbreaking products to the market.
