The monolithic panel can be scaled up in size without increasing the thickness of any of the deposited layers. As the width w is increased, each strip cell is lengthened so that the panel current is increased (see Fig. 16). As the length of the panel / is increased, the number of strip cells increases and so does the panel voltage. Since the interconnections are made by the laser scribing process, the inactive area of the panel can be limited to 1 - 2% (Hanak, 1981).

COPLANAR FUEL CELL DESIGN STRIP CELLS... 

The electrodes in coplanar cells are mostly either a pair of parallel straight lines (strips) or multiple such strips (Figure 18.1—hence the often-used term strip cells). Sometimes more complicated electrode patterns are used [e.g., comblike interdigitated structures (Figure 18.2)]. In strip cells, typically, the widths of the electrodes and the gaps range from tens of a micrometer to a few millimeters.

The earliest references connected with strip cells ( surface migration cells ) seem to be in a report by Van Gool in 1965 and in a patent issued to Louis et al. in 1979. The terms surface-diffusion and surface-migration cells sometimes used for strip cells are not quite accurate since ion migration in the gap between anodes... 

The main advantage of the coplanar fuel cell design is the possibility of considerably reducing the internal ohmic resistance of the cell, which is due primarily to the ohmic resistauce of the electrolyte. To decrease the ohmic resistance of conventional MEAs it is necessary to reduce the thickness of the electrolyte. An excessive reduction of this thickness can have detrimental consequences the formation of cracks and pinholes and the loss of stability and gas-tighmess. In strip cells the ohmic resistance is determined by the width of the gap between cathodes and anodes and can be decreased simply by narrowing this gap. If the electrodes are micropattemed to be close together, the cell s power density can be increased considerably.
