Toyota Motor (Toyota) is the leading patent filer in fuel cell fault monitoring, followed by Hyundai Motor. One of Toyota's latest innovations in FCEV fault monitoring is a new system that uses artificial intelligence (AI) to predict problems and identify potential causes. This system is still under development, but it has the potential to revolutionize FCEV fault monitoring by making it more accurate, proactive, and cost-effective. Another new innovation from Toyota is a fuel cell fault monitoring system that uses blockchain technology to store and transmit data. This system is designed to be more secure and tamper-proof than traditional systems, and can also be used to track the performance of FCEVs over time. Some other significant patent filers in the space include Panasonic, Kia, and Gogoro.

In terms of application diversity, AES leads the pack, while TE Connectivity and Kiekert stood in the second and third positions, respectively. By means of geographic reach, AES held the top position, followed by BYD and Gogoro.
