In a solid-oxide fuel cell assembly, a co-flow heat exchanger is provided in the flow paths of the reformate gas and the cathode air ahead of the fuel cell stack, the reformate gas being on one side of the exchanger and the cathode air being on the other. The lens includes a first surface and a second surface. The process optionally includes heating of the surface of the photopolymerizable layer. During programming, the antifuse transistor is turned on which melts the underlying silicon and causes a permanent reduction in the transistor’s resistance. The lipoprotein profile can be used in clinical diagnoses and other medical applications.
