Solution Approach 1:

A heat exchanger is introduced as an intermediary component between the electrolysis cell and the environment. The heat exchanger transfers thermal energy from the electrolyte solution to a cooling fluid, thereby controlling the temperature of the electrolyte solution during electrolysis without directly interfering with the electrochemical reaction process

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses the electrical energy already supplied to the electrolysis cell to also power the cooling mechanism. The control system monitors temperature and automatically adjusts the cooling fluid flow or electrical input to maintain optimal temperature, making the system self-regulating

Inventive Principle:
Principle #25Self-service

Solution Approach 1:

The thermal energy that initially poses a hazard is converted into a beneficial control parameter. By using the heat exchanger and control system, the temperature rise is prevented from becoming hazardous while the controlled thermal management ensures stable electrolysis operation and safe hydrogen-oxygen mixture generation

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

A control system continuously monitors the temperature of the electrolyte solution and adjusts the electrical energy input or cooling fluid flow accordingly. This feedback mechanism ensures that temperature remains within safe limits, preventing hazardous conditions while maintaining efficient oxyhydrogen generation

Inventive Principle:
Principle #23Feedback
