TL;DR: In this paper, an integrated air conditioning and hot water supply system for conditioning air and supplying hot water to a building is described, which incorporates a hot water tank in the system which feeds a heat exchanger to heat air which is recirculated from the building when required during cool weather periods.

TL;DR: In this article, a method of flowing reactants over an ion exchange membrane in a fuel cell flow field plate is provided, comprising a network of flow channels in the plate bounded by an electrochemically active electrode, the network comprising a series of passages having parallel grooves, the passages being interconnected by a header providing a substantially even redistribution of fluid flow received from grooves of one passage togrooves of the next passage.

TL;DR: In this paper, a combined heat and power, or cogeneration, system combining a fuel cell for generating electrical power with a thermal power source was described, the system comprising: a fuel processor for converting a hydrocarbon fuel into hydrogen in an output stream, the hydrogen rich output stream containing a low content of carbon monoxide; a high temperature hydrogen fuel cell system tolerant to low carbon dioxide content of up to 5% receiving the output stream and an oxidant fluid stream; and a heat exchange system having a first module associated with the fuel processor and a second module connected at least

TL;DR: A fuel cell power system has at least one stack assembly having a clamp mechanism for holding plates of the fuel cell stack together, a fuel supply and exhausting stream, an oxidant supply, and a cogeneration heat exchanger as discussed by the authors.
