Floating membraneless PV-electrolyzer based on buoyancy-driven product separation
Using asymmetrically catalyst coated mesh mebranes at small separation distances, vertically hanging mesh electrodes can perform electrolysis without a membrane and get good product separation, using natural gas buoyancy. Though this skews to tall rigs.

Carbon-based Catalyst Developed for Fuel-cell Forklifts - News - Solar Power Plant Business
Ballard Power Systems seems to be the source of these carbon nanoshell catalyst electrodes, but one of the original researchers is Junichi Ozaki, of Gunma University, who was pursuing nano-shell multilayer carbon hollow shell spheres.

Carbonized-leaf Membrane with Anisotropic Surfaces for Sodium-ion Battery - ACS Applied Materials & Interfaces (ACS Publications)
So a baked oak leaf turns out to be a decent sodium battery electrode. A bioengineered oak leaf that is easier to harvest/use would be an interesting base from which to build battery parts.

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.

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.

Sumitomo Electric Industries, Ltd. | Press Release (2011) Development of Porous Aluminum “Aluminum-Celmet”

Stanford researchers use river water and salty ocean water to generate electricity
This is not an osmotic pressure power generator, rather a battery with flushable electrolytes that determine if it is in a charge or discharge phase. The added trick is using nanorods to increase the electrode area. Salinity is key here, meaning it doesn't have to be really clean freshwater, but the battery prefers brine over saltwater or brackish water. Hrm, I wonder if you could do this as secondary power generation for water desalination plants located on rivers next to oceans or salt lakes, using freshwater sources and desalination output brine?

Batteries charge very quickly and retain capacity, thanks to new structure | News Bureau | University of Illinois
Interesting, using Styrofoam beads as a temporary lattice building framework to make a metal lattice, which is later covered with the final thin film. This creates a very high surface area, allowing super fast charging. But, still like SCiB batteries, it seems the energy density is lower than conventional electrode batteries of the same type (around 75%) . A worthy flaw to allow fast charging? But that doesn't get around the high amperage issues of fast charging, and there is the scary part about fast accidental discharge, so you face the same issues as ultracapacitors.

[JSAP] Optical Fiber Turns Into Solar Cell -- Tech-On!
Interesting hybrid cascade/tandem solar cell architecture using fiber optics. The trick is to catch light bouncing in the fiber by dye sensitized solar cells mounted as a concentric cladding around the fiber. To get higher efficiency, have one band of cells of a length sufficient to cat most pounced light in a single pass, then have another band farther down the fiber optimized for a different wavelength for the second pass. You would have multiple bands from front to back with short wavelength stuff up front. Interesting that these guys are gunning for the near-infrared, as they use bounced light which doesn't suffer from transmittance problems encountered in transparent electrode TCO dye sensitized tandem cells which must pass through the first layer to reach lower layer cells.
