Solution Overview
Problem
Current technologies do not effectively clarify the pipe structure for efficiently supplying hydrogen or electric power between a fuel cell vehicle and a stationary fuel cell system, leaving room for improvement in power supply during outages or emergencies.
Innovation Solution
A multi-cylindrical structure supply pipe comprising concentric pipes for hydrogen, liquid circulation, and electric wires, which allows for the efficient transfer of hydrogen, liquid, and electric power between a stationary fuel cell system and an in-vehicle fuel cell system, including a hydrogen supply pipe, a liquid circulation pipe, and an electric wire pipe, with reinforcement layers and heat exchanger functionality.

Engineering Contradiction Analysis
1Device complexity
If multiple separate pipes are used for hydrogen supply, liquid circulation, and electric wire transmission, then each component can be optimized independently, but the overall system complexity increases and space efficiency decreases
Solution Approach 1:
The patent combines hydrogen supply pipe, liquid circulation pipe, and electric wire pipe into a single integrated multi-cylindrical structure supply pipe. The inner cylinder accommodates the hydrogen supply pipe, the middle cylinder accommodates the liquid circulation pipe, and the outer cylinder accommodates the electric wire pipe, allowing multiple functions to be transmitted through one unified structure.
Solution Approach 2:
The patent employs a nested cylindrical structure where the inner cylinder is placed within the middle cylinder, which is in turn placed within the outer cylinder. This nested arrangement allows the hydrogen supply pipe, liquid circulation pipe, and electric wire pipe to be housed in concentric layers, maximizing space utilization and reducing overall system complexity.
2Volume of moving object
If a compact multi-cylindrical structure is used to reduce space, then space efficiency improves, but manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The supply pipe is divided into three separate cylindrical components (inner cylinder, middle cylinder, outer cylinder) that can be manufactured independently using standard piping processes. Each cylinder is designed to fit within the next larger cylinder, allowing for modular manufacturing and assembly while achieving a compact final structure.
Solution Approach 2:
The multi-cylindrical structure serves multiple functions simultaneously: the inner cylinder for hydrogen supply, the middle cylinder for liquid circulation, and the outer cylinder for electric wire transmission. This universal design consolidates what would traditionally require three separate pipe assemblies into one integrated component, reducing overall volume without sacrificing manufacturing feasibility.
3Volume of moving object
If concentric cylindrical layers are used to integrate multiple functions, then space utilization improves, but heat dissipation and fluid flow management become more challenging
Solution Approach 1:
The patent applies different thermal management characteristics to different cylindrical layers. The inner cylinder handling hydrogen supply can be designed with specific thermal insulation or conduction properties, while the middle cylinder for liquid circulation can be configured to facilitate heat exchange. This localized thermal management allows each layer to be optimized for its specific function while maintaining the compact concentric structure.

AI summary
A multi-cylindrical structure supply pipe includes at least three concentric pipes that couple a stationary fuel cell system that is stationary and an in-vehicle fuel cell system mounted on a fuel cell vehicle. The at least three concentric pipes include a hydrogen supply pipe, a liquid circulation pipe, and an electric wire pipe. The hydrogen supply pipe is configured to allow hydrogen gas to flow through the hydrogen supply pipe. The liquid circulation pipe surrounds an outer periphery of the hydrogen supply pipe. The liquid circulation pipe is configured to allow liquid to flow through the liquid circulation pipe outside the hydrogen supply pipe. The electric wire pipe surrounds an outer periphery of the liquid circulation pipe. The electric wire pipe is provided with one or more electric wires outside the liquid circulation pipe.
