Self-Regulating Water-Separator System for Fuel Cells
This system would not depend on hydrophobic or hydrophilic surfaces.
A proposed system would perform multiple coordinated functions in regulating the pressure of the oxidant gas (usually, pure oxygen) flowing to a fuel-cell stack and in removing excess product water that is generated in the normal fuel-cell operation. The system could function in the presence ...

Spiral Orbit Tribometer
Friction and lubricant degradation rate can be quantified rapidly.
The spiral orbit tribometer (SOT) bridges the gap between full-scale life testing and typically unrealistic accelerated life testing of ball-bearing lubricants in conjunction with bearing ball and race materials. The SOT operates under realistic conditions and ...
