Project ESA Tender AO/1-6353/10/NL/JC - Energy provision and Management study Object Study on the development of RegeneraWve Fuel Cell Technology for per «Space ExploraWons», based on Polymer Electrolyte Fuel Cell (PEFC). The project framework is the Aurora Project, for human explorawon of space. AcWviWes Trade-off Analysis of PEFC technology for space (lunar) applicawon Commercial MEA selecwon based on performance in design condiwons DefiniWon of the best operawve condiwons for the selected MEA Design, realizawon and teswng of 1 kw PEFC stack (2 modules of 500W) PolarisaWon, Wme-test and orientawon teswng Design, realizawon and test of 1 kw system in Stand-Alone (FC) configurawon Design, realizawon and test of 1 kw system in Closed-Loop (FC-EZ) configurawon for stawonary (LB) and mobile (PLR) space applicawons.

PEFC in space Study on the development of RegeneraWve Fuel Cell Technology for per «Space ExploraWons», based on Polymer Electrolyte Fuel Cell (PEFC) (project framework is the Aurora Project, for human explorawon of space). A lunar base designed to generate power from PV during daywme and store excess energy as H2 and O2 for the 14-days long night. The target was to design three different breadboards with two 500 W stacks fed with pure hydrogen and oxygen to test the performance, durability and criwcal issues of PEFC technology operawng under space condiwons MEA and auxiliary components had to be standard elements.
Most recent acwviwes Project TESEO 2 x 2,5 (3,5 peak) kw stacks (H 2 /ambient air) On-board power for marine applicawon Includes solid hydrogen storage tanks Low cost and reliable hydrogen sensors for safety CollaboraAon with Mexico Handheld low cost passive air-breathing stack Closed-Loop low power stack Underwater marine applicawon for long term unarended standalone operawon, storage, target geo-physical environmental monitoring
