Toyota Jidosha Kabushiki Kaisha has filed a patent titled “A Vehicle Including a Fuel Cell Stack, Radiator, and Hydrogen Storage System” on August 8, 2024. This patent outlines a novel design aimed at optimizing hydrogen fuel cell efficiency and vehicle cooling systems.

Unique Features and Improvements:

The standout feature of Toyota’s patent is the integration of a cooling channel within the hydrogen manifold. Unlike traditional designs where cooling and hydrogen supply systems operate independently, this integrated approach enhances the thermal management of the fuel cell stack. Secondly, the multiple gas tanks connected via a manifold improve hydrogen storage efficiency and safety, addressing issues of uniform hydrogen distribution.

Potential Applications:

This patented technology is primarily designed for automotive applications, particularly in hydrogen fuel cell electric vehicles (FCEVs). However, the principles could be extended to other fields such as stationary fuel cell systems and heavy-duty machinery, providing advanced cooling and efficient hydrogen storage.

The impact on the hydrogen market could be significant. The design promises enhanced fuel cell efficiency and longer lifespan of the fuel cells due to better thermal management. This can lead to less frequent maintenance and potentially lower costs for end-users. Additionally, making FCEVs more reliable and efficient may accelerate market adoption, contributing to the broader shift towards sustainable energy solutions.

Technical Specifications and Processes:

The patent details the use of a radiator that cools the coolant circulated through the fuel cell stack, ensuring optimal temperatures are maintained. The manifold connects multiple hydrogen gas tanks, and the cooling channel within this manifold circulates coolant to modulate the temperature of the hydrogen gas before it enters the fuel cell stack. This process not only aids in maintaining the efficiency of the fuel cell stack but also ensures safety by preventing excessive heat buildup in the hydrogen storage system.
