La finalitat del projecte va ser dissenyar una tapa amb les mesures justes perqu\u00e8 hi haguessin tres forats espec\u00edfics, dos dels quals siguin per a l’entrada i sortida de gasos i l’\u00faltim amb la geometria adequada per permetre connectar el circuit el\u00e8ctric, que en aquest cas per a una cel\u00b7la electroqu\u00edmica posseeix: un el\u00e8ctrode de treball (Ag o C),\u00a0 un el\u00e8ctrode de refer\u00e8ncia (pseudo d’Ag) i un contrael\u00e8ctrode (Carboni). El problema \u00e9s que la configuraci\u00f3 interna ha d’estar a\u00efllada dels l\u00edquids, que puguin topar el circuit el\u00e8ctric per la qual cosa la tapa t\u00e9 un turonet especial que nom\u00e9s permet el pas dels el\u00e8ctrodes a la part interna de la cel\u00b7la i aix\u00ed optimitzar el temps de vida del circuit, la quantitat de l\u00edquid i\u00f2nic emprat i reduint temps d’operaci\u00f3 en el muntatge de la configuraci\u00f3<\/p>\n\n\n\n

Un dels reptes ha sigut poder trobar el material idoni per poder treballar en aquetes condicions. La primera prova dimensional es va realitzar amb el material m\u00e9s com\u00fa, el PLA. Per\u00f2 de seguida vam poder comprovar que el seu comportament amb els qu\u00edmics, afectava a la seva estabilitat dimensional.<\/p>\n\n\n\n

Ens vam decantar per utilitzar el PP, amb els inconvenients intr\u00ednsecs d’aquest material. El principal problema va ser trobar la manera d’adherir la pe\u00e7a a la superf\u00edcies de treball, provant des de laques, esprais i barres, fins arribar a al millor soluci\u00f3, que va ser aplicar una primera capa cinta adhesiva d’embalatge en base PP.<\/p>\n\n\n\n
