An inter-connector interposed between two serially connected unit cells provides mechanical strength and conductivity to the serial connection between the unit cells. Embodiments of the inter-connector comprise a supporting frame providing mechanical support for the two unit cells; a welding projection for welding the interconnector to a unit cell; and a welding projection surrounding area located between the welding projection and the supporting frame, wherein the supporting frame is thicker than the welding projection surrounding area, and the welding projection is thicker than the welding projection surrounding area.

A serial interface interposed between two serially connected unit cells provides mechanical strength to the serial connection and conductive coupling therebetween. The serial interface includes an inter-connector having a first vent hole formed therein configured for conductively coupling an anode outer wall of a first unit cell and a cathode terminal of a second unit cell to each other; and a spacer having a second vent hole formed therein and configured to be disposed between the inter-connector and an anode outer wall of the second unit cell to prevent a short-circuit due to the movement of the inter-connector.

An error correction method and apparatus for correcting multiple errors in received digital data word signals calculates syndromes S.sub.0, S.sub.1, S.sub.2 and S.sub.3 from a block of n received data words and a parity check matrix H. First coefficients .sigma..sub.1 and .sigma..sub.2 are calculated from the derived syndromes and a second coefficient K is calculated from the first coefficients .sigma..sub.1 and .sigma..sub.2. An error location value x.sub.1 is calculated from the second coefficient K, actual error location values X.sub.1 and X.sub.2 are calculated from the value x.sub.1, and error values Y.sub.1 and Y.sub.2 are calculated from the actual error location values X.sub.1 and X.sub.2. The received data words are then corrected by applying the calculated error values Y.sub.1 and Y.sub.2. The error location value x.sub.1 calculator is preferably constituted by logic gates which enable the apparatus to be smaller and faster than those using a conventional ROM table.
