Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel cell assembly 100 containing at least one fuel cell 118 including at least two electrodes 112, 116 and an electrolyte 114. SOLUTION: An interconnection structure 102 includes at least one flow channel 104 initially defined by a removable sacrificial material 110. A method of forming the fuel cell assembly includes the steps of providing the interconnection structure having at least one flow channel, depositing the sacrificial material into the flow channel, depositing an electrode or an electrode/electrolyte material upon the interconnection structure and the sacrificial material, and processing the fuel cell so as to remove the sacrificial material.
