Fuel Cell Vehicle Communication Device Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel cell vehicle filling systems face challenges in effectively preventing fuel gas leaks and ensuring reliable communication between the vehicle and the nozzle, which can lead to adverse effects on the communication device due to exposure to fuel gas.
Innovation Solution
The fuel cell vehicle incorporates a vehicle side communication device positioned deeper than the bottom wall of the fuel inlet box and shielded by a partition wall, allowing for wireless communication with the nozzle while preventing fuel gas exposure and ensuring effective shielding of the communication device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle side communication device is positioned closer to the nozzle for better communication, then communication reliability improves, but exposure to fuel gas increases causing adverse effects
Solution Approach 1:
The communication device is positioned on the outer circumferential side of the receptacle rather than directly adjacent to the nozzle, changing the spatial dimension of placement. This lateral positioning combined with deeper placement creates sufficient distance from fuel gas sources while maintaining communication functionality through the housing structure.
Solution Approach 2:
The housing structure acts as an intermediary barrier between the communication device and fuel gas. The partition wall within the housing further mediates this protection, allowing the communication device to operate reliably while being shielded from harmful fuel gas exposure.
2Object-affected harmful factors
If the communication device is shielded deeper within the housing, then protection from fuel gas improves, but communication signal strength may deteriorate
Solution Approach 1:
The housing structure serves multiple functions simultaneously: it provides mechanical support, creates the recessed positioning for the communication device, and acts as a protective barrier against fuel gas. The partition wall adds another layer of protection while maintaining signal transmission capability.
Solution Approach 2:
The housing and partition wall provide selective protection - they shield the communication device from fuel gas while allowing communication signals to pass through. This localized quality differentiation protects critical components without compromising overall system functionality.

Function Achieved in This Case
This configuration secures a sufficient interval between the nozzle and the communication device, reducing adverse effects from fuel gas leaks and enhancing the reliability and durability of the communication system by shielding the device from hydrogen gas.
Implementation Method 1
The communication filling system is configured to implement infrared communication between a nozzle on a station side, and a receptacle on a fuel cell vehicle side. Specifically, a transmitting element configured to transmit (emit) infrared light is provided to the receptacle, and a receiving element configured to receive this infrared light is provided to the nozzle

AI summary
A fuel cell vehicle includes a fuel cell, a storage device, a receptacle, a housing, and a vehicle side communication device. The housing has a bottom wall recessed from a surface of a body of the fuel cell vehicle by a predetermined depth. The receptacle protrudes from a bottom face of the bottom wall to an inner space of the housing. The vehicle side communication device is provided to the housing on an outer circumferential side of the receptacle. The vehicle side communication device is configured to wirelessly communicate with a nozzle side communication device provided to a nozzle. The vehicle side communication device is disposed on a deeper side than the bottom face of the bottom wall and/or is disposed via a partition wall configured to shield the vehicle side communication device from fuel gas in the inner space.
