The objectives of the APOLLON-B consortium are the development of materials for High Temperature PEMFCs, functional at temperatures 130-200oC. Their application will permit their efficient operation under H2/H2 re-formate, aiming to power densities of 0.5W/c m2 at cell voltage between 0.5-0.6V and significantly reduced manufacturing cost of MEAs.
The accomplishment of these objectives will be succeeded by:
(1) Further development, optimisation and novel synthesis of HT polymer electrolyte membranes.
Three types of novel PEMs will be developed:
(i) H3PO4 doped PEMs based on polymers and polymer blends containing imidazol or pyridine groups in their main chain,
(ii) polymers containing polar groups with high pKa (>7) that bound H3PO4 strongly,
(iii) Strong base doped membranes based on imidazol groups containing polymers,
(iv) Non-doped self sustained Organic acid-base composite electrolytes with operating temperatures above 150oC and
(vi) SiWA/Ormolyte type ureasil membranes.
(2) Development of non-noble electrocatalysts Non Pt containing electrocatalysts are proposed both for acid and base doped PEMs. Fot the acid doped membranes Cu/CeO2 or Cu/MnO2 supported anode electrocatalysts (active and quite stable in H2SO4 solutions) and WC or other metal carbides combinations can be considered as candidates for anodic materials, while Fe or Co based electrocatalysts of the FeNx/C type exhibit similar electrocatalytic activity to Pt/C for O2 reduction. The concept of the base-doped PEMs allows for the proposal of alternative electrocatalytic materials, like H2 storage alloys of AB2 (ZrNi2) or AB5 (LaNi5) type as anodic and perovskites LaNiO3 or LaSrCoFeO as cathodic electrodes.
