V tomto „Pl\u00e1nu pro budoucnost trhu s vod\u00edkem“ se v podrobn\u00e9m rozhovoru vyjad\u0159uj\u00ed dva odborn\u00edci spole\u010dnosti Freudenberg: J\u00fcrgen Emig, \u0159editel p\u0159edv\u00fdrobn\u00edho v\u00fdvoje vod\u00edkov\u00fdch aplikac\u00ed, a Dr. Dominik Kraus, vedouc\u00ed odd\u011blen\u00ed lisovac\u00edch technologi\u00ed. <\/p>\n\n

Aby bylo mo\u017en\u00e9 bodovat z hlediska trvale spolehliv\u00e9ho t\u011bsnic\u00edho \u00fa\u010dinku, odolnosti v\u016f\u010di m\u00e9di\u00edm a propustnosti, je obvykle nutn\u00e9 p\u0159epracovat t\u011bsnic\u00ed materi\u00e1ly a konstrukce. Spole\u010dnost Freudenberg Sealing Technologies ji\u017e v t\u00e9to oblasti dos\u00e1hla zna\u010dn\u00fdch \u00fasp\u011bch\u016f. „Lid\u00e9 \u010dasto mysl\u00ed nejprve na silikon, ale pokud jde o \u017eivotnost, silikon nesta\u010d\u00ed. Silikon nen\u00ed v\u016fbec vhodn\u00fd nap\u0159\u00edklad pro palivov\u00e9 \u010dl\u00e1nky pracuj\u00edc\u00ed p\u0159i vysok\u00fdch teplot\u00e1ch. Proto jsme vyvinuli vlastn\u00ed materi\u00e1ly speci\u00e1ln\u011b pro aplikace v palivov\u00fdch \u010dl\u00e1nc\u00edch,“ vysv\u011btluje Emig. 35 FCPO 100 je vlastn\u00ed v\u00fdvoj, kter\u00fd je z hlediska zpracov\u00e1n\u00ed podobn\u00fd tekut\u00e9mu silikonu. 70 FKM 256261 je materi\u00e1l, kter\u00fd spole\u010dnost vyvinula speci\u00e1ln\u011b pro po\u017eadavky PEM elektrol\u00fdzy a vysokoteplotn\u00edch PEM palivov\u00fdch \u010dl\u00e1nk\u016f. <\/p>\n\n

Zvl\u00e1\u0161tn\u00edm probl\u00e9mem je, \u017ee paraleln\u011b existuj\u00ed r\u016fzn\u00e9 technologie elektrol\u00fdzy a palivov\u00fdch \u010dl\u00e1nk\u016f a pro \u017e\u00e1dnou z nich dosud nebyly stanoveny normy. „Co se t\u00fd\u010de konstrukce desek, nen\u00ed trh v sou\u010dasn\u00e9 dob\u011b t\u00e9m\u011b\u0159 standardizov\u00e1n,“ popisuje situaci Kraus. Pot\u0159ebn\u00e9 jsou proto univerz\u00e1ln\u011b platn\u00e9 specifikace pro konstrukci desek, kter\u00e9 zjednodu\u0161\u00ed aplikaci t\u011bsn\u011bn\u00ed a urychl\u00ed tak proces. Slovy Emiga: „T\u011bsn\u011bn\u00ed 3D struktur je v\u00fdzvou. Pokud se zohledn\u00ed a standardizuj\u00ed ur\u010dit\u00e9 po\u017eadavky, je \u0161ance na dosa\u017een\u00ed robustn\u00edho t\u011bsn\u011bn\u00ed velmi vysok\u00e1. Bylo by \u017e\u00e1douc\u00ed v\u00edce standardizovat konstruk\u010dn\u00ed prvky, pak bychom snad ji\u017e mohli vyr\u00e1b\u011bt mnohem v\u011bt\u0161\u00ed mno\u017estv\u00ed n\u00e1kladov\u011b efektivn\u011bji.“ <\/p>\n\n
