Performance analysis of polymer electrolyte membrane (PEM) fuel cell stack operated under marine environmental conditions

Performance of individual cells in an operating polymer electrolyte membrane (PEM) fuel cell stack is different from each other because of inherent manufacturing tolerances of the cell components and unequal operating conditions for the individual cells. In this paper, first, effects of different operating conditions on performance of the individual cells in a two-cell PEM fuel cell stack have been experimentally investigated. The results of the experiments showed the presence of a voltage difference between the two cells that cannot be manipulated by operating conditions. The temperature of the supplying air among others predominantly influences the individual cell voltages. In addition, those effects are explored by using a dynamic model of a stack that has been developed. The model uses electrochemical voltage equations, dynamic water balance in the membrane, energy balance, and diffusion in the gas diffusion layer, reflecting a two-phase phenomenon of water. Major design parameters and an operating condition by conveying simulations have been changed to analyze sensitivity of the parameters on the performance, which is then compared with experimental results. It turns out that proton conductivity of the membrane in cells among others is the most influential parameter on the performance, which is fairly in line with the reading from the experimental results.

The present work consists of the modeling and analysis of solar photovoltaic panels integrated with electrolyzer bank and Polymer Electrolyte Membrane (PEM) fuel cell stacks for running different appliances of a hospital located in Kolkata for different climatic conditions. Electric power is generated by an array of solar photovoltaic modules. Excess energy after meeting the requirements of the hospital during peak sunshine hours is supplied to an electrolyzer bank to generate hydrogen gas, which is consumed by the PEM fuel cell stack to support the power requirement during the energy deficit hours. The study reveals that 875 solar photovoltaic modules in parallel each having 2 modules in series of Central Electronics Limited Make PM 150 with a 178.537 kW electrolyzer and 27 PEM fuel cell stacks, each of 382.372 W, can support the energy requirement of a 200 lights (100 W each), 4 pumps (2 kW each), 120 fans(65 W each) and 5 refrigerators (2 kW each)system operated for 16 hours, 2 hours,15 hours and 24 hours respectively. 123 solar photovoltaic modules in parallel each having 2 modules in series of Central Electronics Limited Make PM 150 is needed to run the gas compressor for storing hydrogen in the cylinder during sunshine hours.
