Current high-pressure hydrogen producing apparatuses face challenges in efficiently generating high-pressure hydrogen while managing moisture and reducing equipment size and complexity.
Innovation Solution
The apparatus consists of a first cell device for water electrolysis and a second cell device for water permeation, allowing high-pressure hydrogen to be generated and efficiently discharged without the need for large equipment, with the second cell unit facilitating moisture permeation from the cathode to the anode side, reducing component count and simplifying the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional water electrolysis apparatus is used to generate high-pressure hydrogen, then hydrogen production is achieved, but the apparatus requires large equipment for moisture discharge and has increased size and complexity
Solution Approach 1:
The apparatus is divided into two distinct cell devices: a first cell device for water electrolysis and a second cell device for moisture discharge. This segmentation allows each device to be optimized for its specific function, enabling compact design while maintaining high hydrogen production efficiency
Solution Approach 2:
The second cell device serves dual purposes: it discharges excess moisture from the electrolysis process and simultaneously prepares feedwater for recycling to the first cell device. This multi-functionality eliminates the need for separate large discharge equipment, reducing overall apparatus size
2Productivity
If conventional water electrolysis apparatus is used, then hydrogen is produced, but moisture management requires additional large equipment
Solution Approach 1:
The second cell device acts as an intermediary between the first cell device and the external environment. It receives moisture-laden gas from the first cell device, separates and discharges excess moisture, and returns purified feedwater to the first cell device, effectively managing moisture without requiring large external discharge equipment
Solution Approach 2:
The system discards excess moisture that accumulates during electrolysis while recovering and recycling the purified feedwater back to the first cell device. This circular approach maintains hydrogen production efficiency while preventing moisture accumulation problems
