This 2017). including the thermodynamics of the cell. The components involved in the construction of PAF Cs such as catalyst, electrolyte and bipolar plates will be discussed.
This implies that phosphoric acid in the electrolyte layer cannot be easily discharged from the fuel cell together with the cell exhaust gas, although even such minute discharge, results in the degradation of cell performance in the long term. A conceptual working principle is described in Figure 1.
Two failure modes of phosphoric acid fuel cells are loss of pho sphoric acid from the membrane and the agglomeration of the platinum particles. It was observed that during the initial stages of PAFC operation, the degradation is largely due to platinum agglomeration. Once the observed because of loss of phosphoric acid from the membrane.
A large number of installations around the world demonstrated that phosphoric acid fuel cells have high reliability, high efficiency and flexibility for a variety of applications.
