... with CCDM architecture has tightly bonded interfaces throughout the assembly, which can result in lower thermal and electrical contact resistances. Considering the fuel cell as a 1D thermal system, the through-plane thermal resistance was observed to decrease by 5–10% when comparing CCDM to CCM...

...Odne S. Burheim; Jon G. Pharoah; Hannah Lampert; Preben J. S. Vie; Signe Kjelstrup We report the through-plane thermal conductivities of the several widely used carbon porous transport layers (PTLs) and their thermal contact resistance to an aluminum polarization plate. We report these values both...

... of 1.625 cm 2 demonstrated a maximum power density of 50 mW ∕ cm 2 at 60 ° C . Since the silicon wafer is too fragile to compress for sealing, and a thicker layer of gold has to be coated on the silicon wafer to reduce contact resistance, further development of micro DMFCs for high power application...
