Molten Carbonate Fuel Cells (MCFC) features lead to their use in combined plant for distributed power and heat generation. Natural gas, biogas, syngas and landfill gas can be exploited as energy and heating sources, because rich of CH4, CO and/or H2. Nevertheless all of them contain variable quantities of H2S, a poisoning gas, responsible of fuel cell component damages. In this work we investigated MCFC single cell performance decay under stress conditions due to use of H2S in the inlet anodic gas. Besides the main parameters (voltage, power, efficiency) it is important to investigate the influence of various work conditions, as fuel mix and the relative pressure of fuel and poison.

Abstract
Molten Carbonate Fuel Cells (MCFC) features lead to their use in combined plant for distributed power and heat generation. Natural gas, biogas, syngas and landfill gas can be exploited as energy and heating sources, because rich of CH4, CO and/or H2. Nevertheless all of them contain variable quantities of H2S, a poisoning gas, responsible of fuel cell component damages. In this work we investigated MCFC single cell performance decay under stress conditions due to use of H2S in the inlet anodic gas. Besides the main parameters (voltage, power, efficiency) it is important to investigate the influence of various work conditions, as fuel mix and the relative pressure of fuel and poison.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
