| Abstract | Liquid water build up in the cathode flow channels of a polymer electrolyte membrane fuel cell (PEMFC) can limit performance. A mechanism that removes accumulating liquid water continuously from the flow channels is required. While a number of water management strategies have been demonstrated, the search for improvements continues. This paper describes a novel technique of using biomimetic design to systematically generate a passive water management system concept for PEMFCs. Studies have shown that biology is a good source of analogies for engineering design. We believe that biomimetic design is an effective design methodology for PEMFC designs due to several common characteristics of biological systems, such as efficient use of material and energy, a self-regulating characteristic, and high tolerance to a wide range of operating conditions. A passive water management solution was generated based on two biological phenomena identified using the biomimetic design method. The biological phenomena inspired use of design elements such as random abrasions and polyethersulfone strands to remove water from the flow channels. The design was demonstrated on a simple test apparatus with low air flow rates and low inlet pressure. Preliminary experiments with the test apparatus have shown total recovery from flow channel catastrophic flooding within seconds. The present paper discusses the biomimetic design process, implementation, and prototype results. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
