Liquid‐fed SOFCs: The direct operation of low‐temperature solid oxide fuel cells (LT㏒OFCs) with liquid fuels is very promising, as they can allow direct utilization of either conventional "drop﹊n" fuels that adapt the existing fuel distribution infrastructure or other liquid fuels (e.g.,...
Disclosed is a separation membrane for direct liquid fuel cells, which is composed of a quaternary ammonium-type anion exchange membrane. The quaternary ammonium-type anion exchange membrane is produced as follows: a polymerizable composition containing a styrene having a haloalkyl group, a cross...
Handling hydrogen as a fuel always is cumbersome, particularly when small or intermediate sized power levels are concerned. Direct methanol fuel cells are an interesting option to provide electric power directly from a liquid fuel providing high energy density and easy handling. Methanol is the simple...
The fuel cell reaction becomes Eq. (8.24), and the performance Eq. (8.25), where g/l denotes vapor or liquid water, and ηi sum up all nonohmic potential losses: (8.24)H2,(g)+12O2,(g)⇒H2Og/l, (8.25)Ecell=Erev−rj−ηi. When operating fuel cells, a few additional ...
Comparing to fuel cells using oxygen as the oxidizer, the replacement of oxygen by H2O2 allows much improved reaction kinetics on the cathode as well as higher power density and theoretical open circuit voltage1,2. The use of liquid fuel is also beneficial to the construction of more compact ...
Among the several types of direct liquid fuel cells (DLFCs) under development with various liquid fuels, the direct methanol fuel cell (DMFC) is in the forefront. However, this technology is currently in a difficult situation. The challe... X Yu,E Pascual,J Wauson,... 被引量: 0发表:...
