Problem with a Fuel Cell

[Fernando Rivas <ferriv@xxxxxxxxxxxxxxx>]

Dear TRNSYS users,

I am trying to simulate a PEM Fuel Cell with IISiBat 3 and I have a 
problem with TYPE170b of Hydrogems
(OXMODE=1, TMODE=1, RTCTMODE=2).  I have the following problem:  the 
A_PEM parameter is "dummy"
and it can not be modified and this value is provided by H_PEM and W_PEM 
parameters (H_PEM * W_PEM = A_PEM).
However if I modify those parameters (H_PEM and W_PEM) and run the 
simulation I get this error message in the list file:
              ********ERROR**********
              TYPE170  TIME =    1.000
      INVALID PEMFC GEOMETRY:
      LENGTH AND/OR HEIGHT NOT IN AGREEMENT WITH AREA!
      A_PEM =  232.00[cm2]
      H_PEM =   16.00 cm
      W_PEM =   16.00 cm
              SIMULATION 'STOPPED'
              ***********************

If A_PEM can not be modified (it has a value by default of 232.00 [cm2] 
always), How can I change the A_PEM value
(in example 16.00*16.00 = 256.00 [cm2])?

Thank you in advance
