but better heat removal is achieved than with air cooling. The advantage of
gas cooling is its simplicity, reliability, and relatively low cost. However, the
size of the cell is limited, and the air-cooling passages are much larger than
the liquid-cooling passages.
9.2.4 PAFC Recent Advances
Various sizes of PAFC are available for stationary applications that meet mar-
ket specications and are generally supplied with guarantees. Cell compo-
nents are being manufactured at scale and in large quantities. Many of these
systems have now run for several years, and so there is a good amount of
operating experience on the reliability of the stack and the quality of power
produced by the systems. The attribute of high power quality a ...
