[TRNSYS-users] electrolyser

Dear all,
We are having some problems in using the type of the electrolyzer. In 
particular the simulation send us a warning message about the IDmax like 
this:
********WARNING********

UNIT 3 TIME = 126.000

TOO HIGH ELECTROLYZER CURRENT = 184.61[mA/cm^2]

MAXIMUM CURRENT DENSITY = 184.00[mA/cm^2]

**********************,

 We calculate the inlet current of the electrolyzer according to the 
production of H2 required by the user. We know that in some cases the 
current may exceed the parameter IDmax but in that case the electrolyzer 
must work at 100%load and so the input IELYshould be the  same (IDMAX).

We have read the code fortrand of the type, but we have not found a 
condition like this :

IF Iely > Imax
   THEN Iely = Imax
.......
So, it is possible to introduce this in the IISiBat Project with a 
particular type or we should modificate the fortrand code of the 
electrolyzer?

Any helps?
Thank you!

Sara and Manu
