A method for synthesizing ternary metal alloy catalysts through solid-state synthesis and thermal diffusion is provided. The method includes forming binary metal alloys through solid-state synthesis, incorporating third metals through thermal diffusion, and annealing under reducing atmospheres to form ternary alloy nanoparticles. The resulting nanoparticles have core-shell structures with selective metal distribution and multiple intermetallic phases. Platinum-rare earth-transition metal systems are formed with enhanced catalytic activity for electrochemical applications. The synthesis approach enables controlled formation of ternary structures previously difficult to achieve through conventional methods, supporting applications in fuel cells and other electrochemical devices requiring improved catalyst performance and durability.

0000 “Purely electrical” solutions to power oscillations involve expensive storage techniques (e.g., batteries and/or capacitors) or wasted energy in “dummy loads” (e.g., resistive banks and/or heaters). Some power delivery systems may incorporate flow batteries as part of the energy storage and delivery solution, particularly using piped electrolyte to distribute power directly to storage racks. For longer duration fluctuations in power consumption, flow batteries may store power during off-peak demand periods and release power during peak demand periods. However, flow batteries typically do not react fast enough to compensate for rapid fluctuations in power consumption. The presently disclosed technology utilizes the pipework of electrolyte distribution systems in place for the flow battery as a distributed electrolytic capacitor. This form of “fast” energy storage is ideally suited to complement “slow” chemical energy storage of a flow battery and is thus capable of acting as a power-smoothing solution and a UPS supplement or replacement.

A monitoring system includes analog-to-digital converters that are isolated from each other and a microcontroller with digital isolation barriers. CAN identifiers (IDs) are hardwired into a harness so that units can be swapped without any reprogramming. Channels are configured to create significant voltage shifts when a voltage sensing wire in a harness is loose or disconnected, and the system responds to such voltage shifts as a fault. Each fuel cell voltage input channel is set up to precisely and accurately measure voltages of plus and minus 250 VDC; however, the fuel cell voltage input channels are tolerant to voltages up to 1500 VDC without damage.
