A solid oxide fuel cell includes a plurality of electric power-generating elements stacked in a stack direction, each including a solid oxide electrolyte and a porous electrode section. Also disclosed is an apparatus comprising two plates substantially parallel to one another and separated by at least about five millimeters, and an antenna coupled to the two plates and configured to transmit or receive a wave having a frequency from about one hundred GHz to about ten THz. Accordingly, when the short message is received by a receiving mobile terminal, the attached identification information allows the receiving mobile terminal to distinguish and process the short message for personal information differently from other general short messages. BD sensors detect the scanned beam. The present invention also describes a method for disinfecting andor cleaning a contact lens comprising contacting a contact lens with a formulation comprising a N-halogenated amino acid salt for a time sufficient to disinfect andor clean the lens. The memory automatically provides status data when a read command is received for a memory array location that is currently subject to a write operation.
