Abstract

Pengaturan purging pada Proton Exchange Membrane Fuel Cell (PEMFC) bertujuan untuk menghindari flooding yang disebabkan adanya penumpukan air pada anoda. Adapun adanya flooding dapat menyebabkan performansi fuel cell menurun, khususnya tegangan stack PEMFC. Oleh karena itu, pada penelitian ini sistem pengaturan purging yang meliputi purging interval (10; 15; 20; 25 dan 30 detik) serta purging time (0,5; 1; 1,5; 2; dan 2,5 detik) dirancang dengan menerapkan beberapa strategi untuk setiap kondisi arus beban pada PEMFC tipe open cathode kapasitas 1 kW. Purging time sebesar 0,5 detik dipilih karena dapat menjaga kestabilan daya dibuktikan dari drop voltage yang kecil. Sedangkan, purging interval yang optimal untuk fuel cell jenis ini yaitu sebesar 15 detik dan 20 detik. Purging interval 15 detik diterapkan untuk arus beban 3 A, 5 A, sedangkan interval 20 detik diterapkan untuk arus beban 1 A, 2 A, dan 4 A. Implementasi pengaturan purging ini mempengaruhi pemanfaatan hidrogen pada fuel cell dimana energi hidrogen terbuang lebih hemat atau lebih sedikit dibandingkan dengan sebelum adanya pengaturan. Selain itu, pengaturan purging juga meningkatkan efisiensi stack dan sistem.

Purging control on the Proton Exchange Membrane Fuel Cell (PEMFC) aims to avoid flooding due to water accumulation at the anode. This flooding leads to a decrease on the performance of the fuel cell, particularly the PEMFC stack voltage. Therefore, in this study the purging control system was designed by implementing several strategies, which includes purging intervals (10; 15; 20; 25 and 30 seconds) and purging time (0.5; 1; 1.5; 2; and 2.5 seconds), for various load current on an open cathode PEMFC with a capacity of 1 kW. The purging time of 0.5 seconds is chosen since it can maintain power stability as evidenced by the small voltage drop. Meanwhile, the optimal purging interval for this type of fuel cell is 15 seconds and 20 seconds. Purging intervals of 15 seconds are applied for load currents of 3 A, 5 A, while intervals of 20 seconds are applied for load currents of 1 A, 2 A, and 4 A. The implementation of this purging control affects the utilization of hydrogen in fuel cells where the wasted hydrogen energy is reduced compared to that before the purging control. In addition, purging control also improves the stack and system efficiency.
