[TRNSYS-users] area of electrode(electrolyser)

Dear Sara,
The IISiBat component file (.tmf) is where the maximum values of the 
parameters are set. You can change them as follows:

1) Open the component file in IISiBat. The easiest way to do this is to 
right click on the component in your project and select "Proforma..."

2) Under the "Variables" tab, click on the button labeled "Variables 
(Parameters, Inputs, Outputs, Derivatives)".

Note: For some reason IISiBat crashes every time I try to do this with some 
components in particular, one of which is the electrolyser (???Can anyone 
help me with this???). If you also experience this problem then you can 
manually edit the .tmf file using a text editor (such as notepad) instead. 
If you would like to know how to do this then let me know.

3) Edit the "max" value of the "AREA" variable to whatever you want 
(something greater than 2.174).

4) Click OK

5) Close the window for the component and click "Yes" when it asks you if 
you want to save changes. You should now be able to change the area to 
values greater than 1 m2.

Regarding Michael Kummert's comment on the model behind the proforma coping 
with such a parameter value... The model should cope fine as far as 
compiling and calculating a result goes, but the question is will it be 
accurate? I believe it will be, provided you set the parameters in the 
external file accurately.

Dear TRNSYS' user,
we have some problems in using trnsys electrolyzer model. We would like to
know if it is possible to modify the electrode area more than 1 m2, in fact 
we need to symulate a 2,174 m2 electrode area component and the range
accepted by the type is 0,... to 1 m2.
Any helps?
Thank you.
Sara e Manu
