Fuel Cell Control TRIZ Cases
- Fuel Cell System Anti-Freezing Control via Circulation Pump
A fuel cell system increases circulation pump flow to prevent pipe clogging from freezing water.
- Dimensional Fluid Mapping via Multifrequency Thermal Excitation
A dimensional fluid mapping system uses multifrequency thermal excitation to generate internal water distribution maps within fuel cell cavities.
- Fuel Cell Stack Local Voltage Reversal Simulation via Hydrogen Starvation
A fuel cell stack simulation method uses blocking members to induce local hydrogen starvation in specific cells.
- Fuel Cell Pump Control for Hydrogen Dilution and Noise Reduction
A fuel cell control unit stops the oxidant pump to retain hydrogen in the cathode during stationary vehicle operation.
- Fuel Cell High Voltage Controller Dedicated Shutdown Wiring
High voltage unit controllers monitor hard shutdown signals via dedicated wire lines to stop operations independently.
- Fuel Cell Bipolar Plate with Actuated Diaphragm Flow Control
Adjustable diaphragms regulate media mass flow and humidity to resolve the trade-off between fixed structure complexity and dynamic power responsiveness.
- Fuel Cell Anode Gas Scavenging via Merged Circulation Passages
A fuel cell system merges circulation passages to manage anode gas flow between cells.
- Fuel Cell Vehicle Scavenging Control via Atmospheric Pressure
Scavenging period setting unit adjusts cathode flow field humidity using atmospheric air pressure data for stable start-up.
- Fuel Cell Maximum Power Calculation During Intermittent Operation
A fuel cell system updates output characteristics using measured current and voltage data to calculate maximum power availability.
- Fuel Cell Stack Segmentation for Current Isolation
Segmenting deteriorated stacks into a sub-power path prevents current concentration on normal stacks, preserving system lifetime.
