Proton exchange membrane fuel cell (PEMFC) operation involves multiphase mass, charge, and heat transport, complex electrochemical reactions, and physical processes that occur at multiple spatial and time scales, e.g., from double-layer effects occurring in milliseconds to catalyst degradation which becomes only significant after many hours of ...

Process control and improvement are keys to successful businesses. A working Experience Factory helps to achieve them but it is not easy to implement. The PROM Experience Manager (PEM) is designed to facilitate such implementation with a flexible visual interface to an experience base populated of metrics collected non invasively.

PASCOOL ELECTRONIC METAHANDBOOK, PEM⋆
International Journal of Solar Energy, 1997In the PASCOOL research program, which is part of the European research project Joule II, one task was dedicated to the development of an interactive software that would summarise the result of the Pascool research program and show the applicability of passive cooling in Mediterranean countries. The aim was to encourage designers to make use of passive

PEM Electrolysis: Ready for Impact
ECS Meeting Abstracts, 2015The need for energy storage has never been so pressing; due to their increasing proliferation and the intermittent nature of wind and solar power sources, many regional grids can no longer accept more of these sources. Electrolysis of water using polymer electrolyte membranes (PEMs) has long held the promise of large-scale energy storage, needing only

PEM fuel cells use a proton conductive polymer membrane as electrolyte. PEM stands for Polymer Electrolyte Membrane or Proton Exchange Membrane. Sometimes they are also called polymer membrane fuel cells, or just membrane fuel cells. This technology has drawn the most attention because of its simplicity, viability, quick start-up, and it has been ...
