TL;DR: In this article, the authors developed thermodynamic, geometric, and economic models for a proton exchange membrane (PEM) fuel cell system for use in cogeneration applications in multi-unit residential buildings.

TL;DR: In this article, a three-electrode system was used to study the effect of anode surface roughness on the performance of microbial fuel cells (MFCs), and two glassy carbon plates were polished to uniform roughness of the orders of magnitude of 10s of nm and 100 s of nm.

TL;DR: In this paper, a decomposition methodology is applied to the synthesis/design optimization of a stationary cogeneration fuel cell sub-system for residential/commercial applications, and the most promising candidate configuration, which combines features of different configurations found in the literature, is chosen for detailed thermodynamic, geometric, and economic modeling both at design and off-design.

TL;DR: In this article, two models of the air-cathode of a PEM fuel cell were proposed using a two-phase non-equilibrium approach, and experimentally determined porosity, capillary pressure relationships, and permeability of the gas diffusion material in order to demonstrate whether or not the use of these properties enhances the accuracy of PEM Fuel Cell models to predict performance curves and liquid water saturation distribution.

TL;DR: In this article, the authors highlight the importance and background of fuel cell seals, discuss the chemical, thermal, and mechanical environments to which fuel cell seal are subjected, and suggest design and testing protocol improvements that may lead to improved fuel cell system performance.
