Fuel cell is similar to battery that can produce electricity almost indefinitely as long as they have fuel to use and can be recharged with fuel. It converts hydrogen and oxygen into electricity, heat, and water. This electrochemical process does not

A new concept that enables fully passive CO2 gas bubble removal in micro direct methanol fuel cells (μDMFCs) is presented. The original concept behind the presented degassing structure (flowfield) is based on microchannels with a T-shaped cross sect

Fuel cells in the low power range can be operated with either hydrogen or methanol as fuel. Requirements with respect to a hydrogen fuel cell for portable applications are outlined. The state-of-the-art of the development of low power stacks and smal

A new flowfield design enabling fully passive CO 2 -gas bubble removal from the anode of a micro direct methanol fuel cell (µ DMFC) is presented. The flowfields channels have an upside down T-shaped cross-section with defined opening angles along th

Realistic modeling of a TPV system is a very demanding task. For a rough estimation of system limits many of assumptions simplify the complexity of a thermophotovoltaic converter. It’s obvious that real systems can not be described by this way. An

A dry-chemical solar cell process has been developed by substituting conventional wet etching steps by reactive ion etching. The performance of mc-Si solar cells that have been made by this new technology is comparable to that of conventionally proce

A zone melting heater (ZMH) was used for oriented recrystallization of thin Si layers which were deposited on different encapsulated ceramic as well as on graphite substrates. The encapsulation consisted of high quality SiO/sub 2/ and SiN/sub x/ laye
