Hydrogen Fuel Cell Exhaust
The majority of automotive hydrogen powered fuel cell vehicles utilize a Proton Exchange Membrane (PEM) fuel cell. Stacks of these cells are used to strip the electrons off of the hydrogen atom, which creates a current flow to power an electric motor and vehicle accessories. To do, so high pressure hydrogen is forced through the “membrane” with the resulting byproduct of pure oxygen and water. Water, water vapor and oxygen are continually emitted from the exhaust; therefore a hydrogen powered vehicle is emission free. Water and vapor management is critical to fuel cell efficiency. Upon shutting the vehicle down the system purges the “stack” of all excess water.
