| 摘要 |
The focus of the invention is a layered structure of high temperature fuel cell system, each fuel cell in the fuel cell system comprising an anode side (100), a cathode side (102), and an electrolyte (104) between the anode side and the cathode side, the fuel cell system comprising the cells in cell stacks (103), air feed-in ducting (120) for feeding air to the cell stacks (103), fuel feed-in ducting (122) for feeding fuel to the cell stacks (103), an afterburner (123) for performing burning of residual gas from the anode side (100), and the fuel cell system comprising potential sources (131) of leakage of explosive gas. The layered fuel cell system structure comprises at least channeling (200) of an exhaust gas containing oxygen, and an ejector structure (127) as nested layers, the ejector structure (127) being innermost, and said ejector structure comprises motive flow nozzle ( 117), suction channeling (150), discharge channeling (151) and a mixing portion (153), said ejector suction channeling being in restricted fluid communication with said channeling (200) of exhaust gas containing oxygen, and the layered fuel cell system structure comprises reactant channeling (105) from anode side (100) outlet to the ejector suction channeling (150) being contained within structures conveying cathode gas. |
