IoT-Based Monitoring System of PEMFC-Solar Cell Hybrid Prototype Power Plant

Proton Exchange Membrane Fuel Cell (PEMFC) is a type of renewable energy-based power plant that produces electricity from harmless chemical reactions. It has several advantages, such as low temperature, fast, applicable for various systems. Meanwhile, the solar cell is also a type renewable energy producing electricity from photon energy of sunlight. These both renewable energy systems have a good potential to be used in Indonesia. However, these renewable energy systems still have several issues to be implemented as a single power plant, such as intermittent and unable to generate electricity at certain times. Therefore, a hybrid system could be a solution for integrating two power plants. This system should be unified as a hybrid power generation system. Then, electrical generation of the hybrid system is necessary to be monitored and evaluated in real time. IoT-based power plant can be implemented as a data logging to monitor electrical power generation. This paper studies a prototype of a small hybrid power plant. The aim of the monitoring system is to evaluate the efficiency of PEMFC-Solar Cell hybrid power plant. The experimental results show that the monitoring system of small hybrid power plant works efficiently.
