Solution Overview
Problem
Conventional hydrogen fuel cell vehicles require a driver to be present to initiate power supply, limiting their use as an external energy source in scenarios like outdated industrial sites or outdoor activities where electricity is unavailable.
Innovation Solution
A power supply system utilizing user authentication through short-range communication (NFC or Bluetooth) to enable a hydrogen fuel cell vehicle to supply electric power to external loads without the driver needing to enter the vehicle, comprising a tagging device, identity authentication unit, power module, battery, and integrated body control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver presence is required to initiate power supply, then safety and control are improved, but ease of operation and accessibility are worsened
Solution Approach 1:
The patent replaces the mechanical key insertion and ignition system with a contactless NFC authentication system. The tagging device reads user information from the user terminal via NFC communication, and the integrated body control unit automatically initiates power supply based on authentication results, eliminating the need for mechanical key operations and driver presence inside the vehicle.
Solution Approach 2:
The patent introduces an intermediary authentication system between the user and the power supply system. The tagging device and integrated body control unit act as intermediaries that verify user identity and authorize power supply automatically, maintaining safety control while enabling convenient remote operation without direct driver involvement.
2Reliability
If driver must enter vehicle to supply power, then security is improved, but adaptability to external scenarios is worsened
Solution Approach 1:
The patent enables the hydrogen fuel cell vehicle to serve multiple functions: it can operate as both a traditional vehicle requiring driver presence and as a remote power supply unit. The power supply system with NFC authentication allows the vehicle to function as a mobile energy source for outdoor activities, camping, and industrial sites where electricity is unavailable, significantly expanding its versatility.
Solution Approach 2:
The patent replaces the mechanical requirement of driver entry with an electronic authentication and control system. The integrated body control unit receives authentication signals from the tagging device and automatically controls power supply to external loads, enabling remote operation while maintaining security through electronic verification of user identity.
3Ease of operation
If contactless authentication is implemented, then ease of operation is improved, but device complexity is worsened
Solution Approach 1:
The patent implements a self-service authentication system where the user simply needs to have their smartphone or terminal with NFC capability near the tagging device. The system automatically reads user information, performs authentication, and initiates power supply without requiring user interaction with complex controls or understanding of system operations, making it extremely easy to use despite the added technology.

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.
