%X Development  of  solid  oxide  cells  (SOC)  over  several  decades  has  led  to  substantial enhancement  of  the  cell  performance  and  a  profound  understanding  of  degradation mechanisms.   Moving   past   the   basic  limitations   caused   by design,   processing  and microstructural issues, it becomes clear that further progress requires application-oriented research   activities    and    cell    designs.   The    optimum   material   combinations   and microstructure  of  a  cell  is  likely  to  differ  depending  on  operational  mode,  intended operation  temperature  and lifetime  as  well  as  between  stationary  and  mobile  application. According  to  these  boundary  conditions,  various  research  topics  have  been  tackled  at Forschungszentrum  Jülich.  On  the  basis  of  the  well-known  anode-supported  cell  (ASC) concept,  electrode  development  and  optimization  of  the  electrolyte  layer  was  performed aiming  at low-temperature  operation  (<600°C).  By  implementation  of  a  GDC electrolyte, for example, the ohmic resistance was reduced by more thana factor of 3. Investigation of highly  active  Ni/GDC  cermets  as  fuel  electrode  are  another  topic  of  investigation.  First progress achieved on metal-supported cells can be transferred for ongoing work to further increase  low-temperature  performance  of  ASCs.  The  material  development  is  aided  by electrochemical  testing  of  symmetrical  cells  and  full-cells  and  supported  by  theoretical considerations of the materials elementary properties.
