Fuel Cell Exhaust Drain Branching to Prevent Water Scattering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fuel cell systems, there is a risk that drain water is discharged from the exhaust path together with exhaust gas and scattered around, posing a potential environmental hazard.
Innovation Solution
A fuel cell system with a drain portion branched from the exhaust path to separate and manage drain water effectively, reducing the risk of scattering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If drain water is discharged together with exhaust gas from the exhaust path outlet, then the discharge structure is simple, but drain water scatters around causing environmental hazard
Solution Approach 1:
The exhaust path is segmented into two separate discharge paths: one for exhaust gas and another for drain water. The drain water discharge path branches off from the exhaust path at a location upstream of the outlet, allowing drain water to be discharged separately through a dedicated discharge port, thus preventing scattering while maintaining structural simplicity
Solution Approach 2:
The drain water discharge function is extracted from the common exhaust path outlet. A separate discharge port is provided on the exhaust path body, allowing drain water to be taken out and discharged independently from the exhaust gas flow, eliminating the harmful scattering effect
