Dual side stack

Kamarudin and coworkers [23] developed a dual side stack where two MEAs were stacked between a gasket, a current collector and anode and cathode plates, as illustrated in Fig. 9.4 (left).

The anode plate at the center of the stack used as a methanol reservoir permit a more efficient fuel distribution and reduces the stack weight. In Fig. 9.4 (right) six dual side stacks were connected in series to generate a 600 mW mobile phone charger that developed a power density of 25 mW.cm. ... 

The initial sampling site (runs 1-12) was an existing 3-in. port on the west side of the south duct leading from the induced draft fan to the stack. This duct was one of two parallel ducts between the electrostatic precipitator and the stack. Three dual tests (13-18) were performed in the north side of the same duct where a 6-in. port had been installed.
