Quality Control of Fuel Cells Channels


Article Preview

The methods of dimensional control for solid surfaces are usually contact methods. However, in fragile and reduced hardness surfaces, these methods present critical disadvantages. The method presented in this work aims to offer resources for the optimization of graphite components machined with laser through the measurement of the channels’ depth and shape. In this scope, the laser triangulation technique demonstrated to be a very useful tool in the quality control of graphite diffusers plates for fuel cell prototyping and in their future production.
