Ozone　in　aircraft　cabin　can　bring　obvious　adverse　impact　on　indoor　air　quality　and　occupant　health.　The　objective　of　this　study　is　to　experimentally　explore　the　ozone　removal　performance　of　flat-type　catalyst　film　by　loading　nanometer　palladium　on　the　activated　carbon　fibers　(Pd/ACFs),　and　optimize　the　configuration　of　ozone　converter　to　make　it　meet　the　design　requirements.　A　one-through　ozone　removal　unit　with　three　different　Pd/ACFs　space　was　used　to　test　the　ozone　removal　performance　and　the　flow　resistance　characteristic　under　various　temperature　and　flow　velocity.　The　results　show　that　the　ozone　removal　rate　of　the　ozone　removal　unit　with　the　Pd/ACFs　space　of　1.5　mm　can　reach　99%　and　the　maximum　pressure　drop　is　only　1.9　kPa　at　the　reaction　temperature　of　200　degrees　C.　The　relationship　between　pressure　drop　and　flow　velocity　in　the　ozone　removal　unit　has　a　good　fit　to　the　Darcy-Forchheimer　model.　An　ozone　converter　with　flat-type　reactor　was　designed　and　processed　based　on　the　one-through　ozone　removal　experiment,　its　ozone　removal　rate　and　maximum　pressure　drop　were　97%　and　7.51　kPa,　separately,　with　the　condition　of　150　degrees　C　and　10.63　m/s.　It　can　meet　the　design　requirements　of　ozone　converter　for　air　purification　and　develop　a　healthier　aircraft　cabin　environment.
