Abstract
An apparatus for dilution of hydrogen concentration in a fuel cell exhaust system is provided. The apparatus includes a fuel cell exhaust line configured for receiving a flow of gas from a connected fuel cell and including a flow of hydrogen gas. The apparatus further includes a mixing chamber disposed to receive the flow of hydrogen gas and configured for mixing a flow of air with the flow of hydrogen gas. The mixing chamber includes a mixing mesh including at least one tab feature configured for altering a flow direction of at least a portion of one of the flow of hydrogen gas and for creating a turbulent flow region within the mixing chamber.
