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. 本发明涉及种具有用于混合燃料和氧化剂的改进的布置的燃料电池系统。本发明涉及种高温燃料电池系统，特别地涉及种固体氧化物燃料电池系统。喷射器具有用于部分未使用氧化剂、部分未使用燃料和部分初级氧化剂的三个入口。喷射器迅速地混合并夹带未使用氧化剂、部分未使用燃料和部分初级氧化剂，混合物在喷射器中驻留的时间小于点燃混合物所需的时间。
