Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydrogen engines rely on external hydrogen sources and lack efficiency in fuel consumption and emission reduction, as they cannot generate their own hydrogen gas.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional hydrogen engines use external hydrogen sources, then the engine can operate with hydrogen fuel, but the system lacks self-sufficiency and cannot generate hydrogen independently
Solution Approach 1:
The system employs a hydrogen generating cell that electrolyzes water to produce hydrogen gas independently, allowing the engine to generate its own fuel supply without relying on external hydrogen sources. This self-service mechanism resolves the contradiction by enabling self-sufficiency while keeping the system integrated and manageable.
Solution Approach 2:
The patent combines the hydrogen generation system (electrolysis cell, water reservoir, pump) with the existing engine fuel system (fuel line, injector, ECU). By merging these functions into an integrated assembly, the system achieves self-sufficiency without proportionally increasing overall system complexity.
2Loss of substance
If hydrogen is introduced into the air/fuel mixture, then fossil fuel consumption is reduced, but the system requires additional components for hydrogen generation and delivery
Solution Approach 1:
The hydrogen generating cell serves multiple functions: it stores water, generates hydrogen gas through electrolysis, and delivers the gas to the engine's fuel system. This multi-functionality reduces the need for separate systems for each function, thereby reducing fossil fuel consumption without proportionally increasing system component count.
Solution Approach 2:
The system recycles water continuously through the hydrogen generating cell, converting it to hydrogen fuel. This recovering approach allows sustained hydrogen production from a single water source, reducing fossil fuel consumption while minimizing the need for additional fuel storage components.
3Productivity
If the hydrogen generating cell uses water electrolysis, then hydrogen gas can be produced on-demand, but energy is consumed from the vehicle's battery
Solution Approach 1:
The system dynamically adjusts hydrogen production based on engine demand. The ECU monitors engine operating conditions and controls the pump and electrolysis cell to produce hydrogen only when needed, optimizing the balance between productivity and energy consumption from the battery.
Solution Approach 2:
The hydrogen generation operates in periodic cycles synchronized with engine operation. The pump and electrolysis cell activate during periods when the engine requires additional hydrogen, and remain dormant when demand is low, thereby maintaining productivity while minimizing continuous battery energy consumption.
