Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fuel cell systems in vehicles experience output degradation over time, necessitating timely replacement to maintain efficiency and reliability, but existing technologies lack effective predictive measures for determining the optimal replacement timing.
Innovation Solution
An information processing device is developed to predict fuel cell output decrease amounts based on use history and characteristic data, allowing for the calculation of deterioration time and notification of appropriate maintenance actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If fuel cell is used continuously without replacement, then operational duration is extended, but output reliability decreases due to deterioration
Solution Approach 1:
The system performs preliminary prediction of fuel cell deterioration using acquired use history information and output decrease characteristic information. By calculating the predicted output decrease amount and predicting the deterioration time before it actually occurs, the system enables advance planning for fuel cell replacement, thus maintaining reliability while extending operational duration through informed decision-making
2Reliability
If fuel cell replacement is performed frequently to maintain output, then reliability is improved, but loss of time and operational efficiency decrease
Solution Approach 1:
The system establishes a feedback mechanism by continuously acquiring use history information, calculating predicted output decrease amounts, and comparing them against threshold values. This feedback loop enables dynamic adjustment of replacement timing decisions, allowing the system to extend operational duration as long as reliability thresholds are met, thereby reducing unnecessary replacements and associated time losses
3Loss of time
If fuel cell replacement is delayed to extend operational duration, then loss of time is reduced, but reliability decreases due to excessive deterioration
Solution Approach 1:
The system performs preliminary calculation of the predicted output decrease amount based on use history and characteristic information before deterioration becomes critical. By predicting the deterioration time in advance and comparing it with the current state, the system determines the optimal replacement timing that maximizes operational duration while maintaining reliability, thus resolving the contradiction between extending duration and preserving reliability

AI summary
An information processing device includes an acquisition unit which acquires use history information indicating a use history of a vehicle, a prediction unit which predicts an output decrease amount based on use history information acquired by the acquisition unit and output decrease characteristic information indicating an output decrease characteristic of a fuel cell in the vehicle according to the use history, and a control unit which executes predetermined processing based on the output decrease amount predicted by the prediction unit. The control unit executes processing of predicting a deterioration time at which a rated output of the fuel cell is equal to or smaller than a threshold value based on changes in the output decrease amount from start of use of the vehicle to present, and outputting information indicating the deterioration time.
