FUEL CELL SYSTEM

摘要

This invention relates to a fuel cell system with an improved arrangement for mixing fuel and oxidant. The present invention relates to a high temperature fuel cell system, in particular to a solid oxide fuel cell system. An ejector is provided with three inlets for a portion of unused oxidant, a portion of unused fuel and a portion of primary oxidant. The ejector mixes and entrains the unused oxidant, a portion of unused fuel and a portion of primary oxidant so rapidly, the time the mixture resides in the ejector is less than the time required for the mixture to ignite.
