Fuel Cell Vehicle Power Output Using Contactless User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydrogen fuel cell vehicles require the driver to be present to operate, limiting their use as a power source in situations where electricity is unavailable, such as outdated industrial sites or outdoor activities.
Innovation Solution
A power supply system using user authentication via short-range communication (NFC or Bluetooth) allows a hydrogen fuel cell vehicle to supply electric power to external loads without the driver needing to enter the vehicle, incorporating a tagging device, identity authentication unit, power module, battery, and integrated body control unit to manage and output power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver presence is required to operate the fuel cell vehicle as a power source, then safety and control are improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The patent replaces the mechanical key insertion and ignition system with a contactless authentication system using NFC or Bluetooth communication. The tagging device reads user information from the user terminal, and the identity authentication unit verifies it against stored authentication information, eliminating the need for physical key manipulation and driver entry into the vehicle.
Solution Approach 2:
The patent introduces an intermediary authentication system consisting of the tagging device, identity authentication unit, and integrated body control unit. This intermediary layer verifies user identity through short-range communication and authorizes power supply without requiring direct physical interaction between the driver and the vehicle's power system.
2Reliability
If driver entry into the vehicle is required for authentication, then security is improved, but convenience and accessibility deteriorate
Solution Approach 1:
The patent replaces the mechanical system of physical key insertion and driver entry with a contactless authentication mechanism. The tagging device communicates with the user terminal through NFC or Bluetooth, allowing authentication to occur remotely without the driver needing to physically enter the vehicle.
Solution Approach 2:
The patent uses a digital copy of the user's authentication information stored in the user terminal (smartphone or similar device) instead of requiring the physical presence of the user. The tagging device reads this digital authentication data, enabling remote authorization while maintaining security through verified identity confirmation.
3Device complexity
If conventional key-based authentication is used, then system simplicity is maintained, but adaptability to modern communication technologies deteriorates
Solution Approach 1:
The patent implements a multi-functional authentication system that supports multiple communication protocols (NFC and Bluetooth) through the tagging device. This allows the system to adapt to different user terminals and communication preferences while maintaining a unified authentication interface, enhancing versatility without significantly increasing operational complexity.
Solution Approach 2:
The patent changes the authentication parameter from physical key insertion to wireless signal transmission and verification. The system detects and processes different types of wireless communication signals (NFC near-field communication or Bluetooth low-energy communication) and adapts the authentication process accordingly, modernizing the system while keeping the overall flow simple.

AI summary
A power supply system of a fuel cell using user authentication includes: a tagging device that receives user information of a user terminal; an identity authentication unit, which compares the user information inputted through the tagging device with previously stored authentication information and outputs a use authority signal when the user information matches the authentication information; a power module complete that produces electric power by a chemical reaction between hydrogen and oxygen; a battery that receives and is charged with electric power produced by the power module complete; an output terminal that is connected to the battery to output electric power stored in the battery; and an integrated body control unit that controls electric power to be outputted through the output terminal when the identity authentication unit outputs the use authority signal.
