CSIRO tech accelerates hydrogen vehicle future - CSIRO
New membrane for extracting hydrogen from ammonia, which allows a hydrogen logistics train where hydrogen is made/stored as ammonia, bulk transport is done as liquid ammonia, and converted back to hydrogen at a local fill station for local storage in a high pressure tank, for eventual use in fuel cell vehicles.

Fuel Cells Finally Find a Killer App: Carbon Capture - IEEE Spectrum
hrm, how hot is the CO2 exhaust? Can you get it to supercritical pressure/temperatures? There's that NETpower allam cycle demo that uses an oxyfuel gas turbine with similar inputs/outputs. The MCFC is more tolerant of inputs, but the allam cycle turbine might have better power output? What is you use a MCFC as a topping cycle replacement of an allam cycle combustor?

Practical Application Limits of Fuel Cells and Batteries for Zero Emission Vessels
Uh, they only cover batteries or liquid/gaseous hydrogen PEM fuel cells in the comparison, so kinda incomplete. So no LNG fuel cells, no fuel cell/microturbine hybrids using the microturbine combustor as a topping cycle. Also, the basic conclusion is huge vessels could run a full trip, but on liquid hydrogen only, and short trip ferries should look at batteries instead.

Protonex | A Ballard Smart Energy Company
Subsidiary of Ballard Power Systems, making military fuel cells. That recent non-platinum catalyst PEM fuel cell announcement for portable applications, for an air cooled PEM fuel cell, sounds familiar. Something similar was being pursued earlier by these guys for LM/DARPA exoskeleton power system work, but suddenly went dark while LiquidPiston ramped up their PR.

Low cost plasma membrane reactor to efficiently convert ammonia to hydrogen
Using a plasma field between an iron tube and palladium foil tube, ammonia can be broken down to nitrogen and hydrogen, with the hydrogen pulled through the palladium foil efficiently, resulting in very high hydrogen gas purity separation. Process is low temperature and pressure as well, though the palladium foil probably isn't cheap. Effectively an ammonia fuel reformer for a hydrogen fuel cell, allowing storage of low pressure ammonia as fuel.

Heteroatom-doped highly porous carbon from human urine : Scientific Reports : Nature Publishing Group
So, um ,wizzing on a slice of coal and slow baking it might make a better fuel cell catalyst than platinum? I wonder if they controlled for diet, since typical korean fare may result in a very different volatile ratio from western food, plus what types of booze. Reminds me of that red wine superconductor research.

The fuel cell for home - Research News June 2014 - Topic 2
Different from Ene-farm rigs, this is an augmented home gas heater, using a reformer and a SOFC fuel cell stack to coproduce power and heat. Not a water heater rig though. Shame you can't chain rig the fuel cell stack with an adsorption cooler plus water heater/space heater.

Towards a ‘proton flow battery’: Investigation of a reversible PEM fuel cell with integrated metal-hydride hydrogen storage
Now that's smart, integrating a metal hydride hydrogen sponge as an electrode in a PEM fuel cell to skip a step. Though it turns the setup essentially into a closed cycle battery, fixed to the capacity of the metal hydride electrode's internal storage capacity, hence the "battery" nomenclature.

Motorbike Generates Electricity Using Its Exhaust Gas -- Tech-On!
Bizarre hybrid device, that uses unburnt hydrocarbons in scooter exhaust gas to heat/run a SOFC fuelcell, which also has thermoelectric elements wrapped around the SOFC tubes to capture waste heat as well. Though my first question would be why use a crappy two/four stroke scooter engine in the first place? Why not a series hybrid powerplant, with a microturbine generator with fuelcell combustor? Though I suppose as an aftermarket mod, as long as it doesn't raise exhaust gas pressure losses too much, it might be an easy conversion...

Launch of New 'Ene-Farm' Home Fuel Cell Product More Affordable and Easier to Install | Headquarters News | Panasonic Global
Um, so they cheated here a bit, and basically entertained the possibility of integrating the fuel cell and storage tank with conventional (i.e. existing) gas fired on-demand hot water heaters which are common in japan, rather than forcing the homeowner to rip out their existing hot water heater. Well, closer to reality is they still have to rip it out, but at least with this setup, you can stick the backup heater into the nook a building was originally equipped with, and stick the fuel cell close to where AC compressors are typically located for a japanese residence.

Silicon wafer based SOFC, claiming 40% direct chemical to electrical efficiency. Apparently Brookstone will be carrying the SOFC as a portable charger pack for small electronics like cellphones.

Wonder how it operates on natural gas, which isn't pure methane...
