Abstract
A dynamic model of a Direct Methanol Fuel Cell is developed in the MATLAB platform. A newly proposed Coefficient Diagram based Proportional Integral Controller (CD-PIC) is designed and its parameters are calculated. The newly designed CD-PIC is implemented in a real time Direct Methanol Fuel Cell (DMFC) experimental setup. Performances in real time operation of the Direct Methanol Fuel Cell (DMFC) are evaluated. The performance of CD-PIC is obtained under tracking of set point changes. In order to evaluate the CD-PIC performances, most popular tuning rules based Conventional PI Controllers (C-PIC) are also designed and analyzed. Set point tracking is carried out for the step changes of ±10% and ±15% at two different operational points. The controller performances are analyzed in terms of Controller Performance Measuring (CPM) indices. The said performance measures indicate that the proposed CD-PIC gives the superior performances for set point changes and found very much robust in controlling DMFC.

Summary
In the present stage of the energy crisis, it has become unavoidable to find out the alternatives for the largely exploited fossil fuels. Different varieties of fuel cells have been developed, the search is on to find out the most promising fuel cell that offers higher efficiency In this context, the Direct Methanol Fuel Cell (DMFC) appears to be the most promising tool to provide power to electronic devices. The Direct Methanol Fuel Cell (DMFC) appears to be the most promising tool to provide power to electronic devices This DMFC is targeted especially to portable applications, where energy and power density are more important than efficiency. The transient response the controller under the control of the caused designer selecting approach is relatively not veryofsensitive to loadisand bounded uncertainties by by variations in the parameter values One.
