Patent ID: 7335431

Claim:
A fuel cell with embedded series/parallel mechanism, which comprises: an anode circuit board including: at least one anode current collector circuit; at least one anode wiring, in which the anode wirings are electrically connected to the anode current collector circuits, respectively; at least one anode pad, and the anode pads are configured at the board edge of the anode circuit board, and the anode pads are electrically connected to the anode wirings; a cathode circuit board, including: at least one cathode current collector circuit; at least one cathode wiring, in which the cathode wirings are electrically connected to the cathode current collector circuits, respectively; at least one cathode pad, and the cathode pads are configured at the board edge of the cathode circuit board, and the cathode pads are electrically connected to the cathode wirings, in which each cathode pad is corresponding to one opposite anode pad; at least one membrane electrode assembly, which are bonded and sandwiched between the anode circuit board and the cathode circuit board, and the membrane electrode assemblies are sandwiched between the anode current collector circuits and the corresponding cathode current collector circuits; at least one U-shape connection terminal, which are clipped between one pair of anode pad and cathode pad in opposite on the anode circuit board and on the cathode circuit board, and the U-shape connection terminal is directly spot-welded and fixed to the paired anode pad and cathode pad without solder welding.
