Title: Steam generator for fuel cell system
Inventor: Andrew Ballard
IPC: H01M8/04
Filed: 2019-08-28
Abstract: A steam generator for a fuel cell system having a heat exchanger with at least one internal heat exchange surface, a water inflow pipe 46, a dripper head 52 with a flow passageway fluidly connected to the water inflow pipe 46. The dripper head 52 extends inside the heat exchanger 52 above the heat exchange surface 60 for feeding water down onto the heat exchange surface for conversion into steam. The dripper head 52 has outlet holes 56 spaced along the flow passageway and between adjacent outlet holes 56 the dripper head has a stepped profile to prevent droplets from adjacent holes coalescing. A fuel inflow pipe can have a section 64 mounted coaxially to a part of the water inflow pipe 46. The fuel inflow pipe’s section can surround the water inflow pipe’s part. The fuel insulates the water to prevent premature steam development. In a fuel cell system with a steam generator, the steam generator can include the fuel inflow pipe, a combined steam and fuel outlet and a reformer directly or indirectly connected downstream of the steam generator.

Title: Sensing apparatus and method of operation thereof
Inventor: HATICE TUNCER
IPC: H01M10/42
Filed: 2019-09-13
Abstract: Terahertz (THz) radiation is passed from a source 310 via a battery to a detector 314. Specifically, the THz radiation passes through a waveguide 308 composed of two electrode 302 layers 304,306, e.g. the anode and cathode in use. The THz radiation can pass through the electrolyte. In the waveguide, the THz radiation interacts with features at the electrode surface, e.g. dendrites or other structural faults. The THz radiation is coupled 312 into the waveguide and exits onto the detector via e.g. a collimating lens 316. Temporal changes in received THz radiation indicate dendrite growth at the electrode surface. A pouch cell may enclose a battery capped with windows suitable for probing the battery with THz radiation in situ (Fig. 4). The THz radiation may be pulsed. It is mentioned that the waveguide may comprise a dielectric, e.g. air.

Title: Controlling range constraints for real-time drilling
Inventor: Srinath Madasu
IPC: G06N7/00
Filed: 2018-05-07
Abstract: A system and method for controlling a drilling tool inside a wellbore makes use of Bayesian optimization with range constraints. A computing device samples observed values for controllable drilling parameters such as weight-on-bit (WOB) and drill bit rotational speed in RPM and evaluates a selected drilling parameter such a rate-of-penetration (ROP) for the observed values using an objective function. Range constraints can be continuously learned by the computing device as the range constraints change. A Bayesian optimization, subject to the range constraints and the observed values, can produce an optimized value for the controllable drilling parameter to achieve a predicted value for the selected drilling parameter. The system can then control the drilling tool using the optimized value to achieve the predicted value for the selected drilling parameter.
