Although, phosphoric acid fuel cell technology is now nearly commercially m
ature, it is mandatory to make it cost competitive with existing power tech
nologies. Since, the cost and power density of fuel cells are linked to eac
h other, attempts are being made to enhance the power density of phosphoric
acid fuel cells. This study demonstrates that phosphoric acid fuel cells w
ith power density values as high as 560 mW cm(-2) are realizable by employi
ng a combination of SiC and ZrSiO4 as an electrolyte matrix, and Pt-Co/C as
a cathode catalyst. (C) 2001 Elsevier Science B.V. All rights reserved.
