Engineering Contradiction Analysis
1Temperature
If conventional electrolyzers use external heaters to increase electrolyte temperature, then the temperature can be increased, but the heating efficiency is low and operational stability is affected
Solution Approach 1:
The heating function is merged with the current collector plates by integrating heating units directly onto them. This combination allows the current collector plates to serve dual purposes: electrical conduction and heating, eliminating the need for separate external heating systems and improving both heating efficiency and operational stability.
Solution Approach 2:
The current collector plates act as intermediaries between the power supply and the electrolyte. By placing heating units on the current collector plates, heat is transferred directly to the electrolyte through the intermediate medium of the current collector plates, achieving more efficient and stable heating compared to external heaters.
2Temperature
If conventional electrolyzers use external heaters, then heating can be achieved, but the heating speed is slow and efficiency is low
Solution Approach 1:
The heating units are merged with the current collector plates, creating an integrated heating system that directly contacts the electrolyte. This merger enables rapid heat transfer from the heating units through the current collector plates to the electrolyte, significantly improving heating speed and efficiency compared to external heating methods.
Solution Approach 2:
The heating function is extracted from the external environment and integrated directly into the electrolyzer structure via the current collector plates. This extraction eliminates heat loss to the external environment and focuses heating energy directly where needed, improving heating efficiency and speed.
