Provided is an electrochemical oxygen reduction catalyst in which a decrease in catalytic activity is suppressed. The present disclosure relates to an electrochemical oxygen reduction catalyst, a manufacturing method thereof, and a fuel cell and a water electrolysis system using the electrochemical oxygen reduction catalyst. The electrochemical oxygen reduction catalyst comprises a catalyst metal having an oxygen reduction activity and an additive that modifies the catalyst metal. The additive contains a nitrogen-containing cyclic organic compound having a triazine skeleton, a polymer thereof, or a cation thereof. In the nitrogen-containing cyclic organic compound, the polymer thereof, or the cation thereof, a total number of functional groups that substitute hydrogen atoms of melamine and functional groups that substitute amino groups of melamine is 3.79 or more and 5.51 or less per molecule of the nitrogen-containing cyclic organic compound.

An NOx concentration estimation method uses an air-fuel ratio sensor in an exhaust system. A first catalyst and an air-fuel ratio sensor are sequentially arranged upstream from a flow direction of exhaust gas flowing through an exhaust passage connected to an engine, and the air-fuel ratio sensor is controllable to an active temperature using a heater. An output value of the air-fuel ratio sensor used for estimating NOx concentration at least when the air-fuel ratio changes from rich to lean is obtained by using a sum of a raw output value of the air-fuel ratio sensor and a predetermined offset value.

A solid-state battery includes: a first electrode layer containing a first electrode active material; an electrolyte layer containing a solid electrolyte and disposed on the first electrode layer; and a second electrode layer containing a second electrode active material and disposed on the electrolyte layer. An Sdr of a surface of the first electrode layer in contact with the electrolyte layer is 9.2% or more.

A rotary electric machine (10;110;210;310;410;510;610) includes a stator core (22) having a plurality of slots (22s), and a three-phase coil (24;124;224;324;424;524;624) including coil segments (80) received in first through sixth layers in the slots (22s). Some of the coil segments received in the third and fourth layers in the same slot (22s) are different from each other in phase. A phase coil (40,50,60;140,150,160; 240,250,260;340,350,360; 440,450,460;540,550,560;640,650,660) of each phase in the three-phase coil (24;124;224;324;424;524;624) includes an inward winding portion (42a,44a,52a,54a,62a,64a; 142a, 144a, 152a, 154a, 162a, 164a;242a,244a,252a,254a,262a,2 64a;342a,344a,352a,354a,362a,364a;442a,444a,452a,454a,462a,464a;542a,544a,552a,5 54a,562a,564a;640a,640c,650a,650c,660a,660c) and an outward winding portion (42b,44b,52b,54b,62b,64b; 142b, 144b, 152b, 154b, 162b, 164b;242b,244b,252b,254b, 262b,264b;342b,344b,352b,354b,362b,364b;442b,444b,452b,454b,462b,464b;542b,544 b,552b,554b,562b,564b;640b,640d,650b,650d,660b,660d). Each of the inward winding portion and the outward winding portion includes an outer-layer connection portion (Ro). Regarding a connection order of the coil segments (80) as seen from side of an input terminal (72, 74, 76) of the phase coil, connection of the coil segments (80) received in the third layer and connection of the coil segments (80) received in the fourth layer are made after the outer-layer connection portion (Ro) in the inward winding portion.

A display control device displays a lane marking image and a host vehicle icon on a display. The display control device includes a travel control unit configured to control travel of a host vehicle, a determination unit configured to determine whether or not the host vehicle is returning to an original travel lane after deviating from the original travel lane, and a display control unit configured to display the lane marking image and the host vehicle icon. When it is determined that the host vehicle is returning to the original travel lane after deviating from the original travel lane, the display control unit moves the host vehicle icon relative to the lane marking image with a position of the lane marking image fixed.

A dashboard cross member lower (30) extending along a vehicle width direction is arranged at a front section and lower side of a vehicle cabin of a vehicle, with a shock absorption member (54) provided inside the dashboard cross member lower. Crash energy from collision load is accordingly absorbed by plastic deformation of the shock absorption member together with the dashboard cross member lower when collision load has been input from the vehicle front.

A vehicle storage battery pack includes: a storage battery cell installed to a vehicle; a lower case that has the storage battery cell mounted thereto and that includes a region separated from a lower face of the storage battery cell, the region configuring a smoke discharge channel; and a heat receiving member that is arranged on a lower face of the lower case and that receives heat of the storage battery cell, wherein the lower face of the lower case at a region configuring the smoke discharge channel is arranged lower than a lower face of the heat receiving member.

A vehicle rear section structure including a storage battery case housing plural storage battery cells, a retaining member arranged at a vehicle front-rear direction rear side of the storage battery case, a smoke discharge vent provided at the retaining member, a first connector made from metal and retained at the retaining member for connecting a first wire thereto, and a second connector made from resin and retained at the retaining member at an opposite side of the first connector from the smoke discharge vent, for connecting a second wire thereto.

A vehicle battery installation structure including an upper cover arranged above an energy storage cell, a cross member spanning in a vehicle width direction above the upper cover, and an equipment case arranged above the upper cover with equipment housed inside the equipment case. The equipment case is fixed to the cross member.

A data acquisition device and a data acquisition method are provided. Each time a traveling speed is acquired during a vehicle performance test, processing circuitry (51) identifies which of multiple divided speed regions (LVR, MVR, HVR) a subject traveling speed belongs to (S31). The subject traveling speed is one of the acquired traveling speeds. It is determined whether a reference value (Van-1) is less than or equal to a provisional criterion value (RVL1 to RVL4) (S41). One of the provisional criterion values (RVL3 and RVL4) that are greater than or equal to a criterion value (RVL) is selected as a selection criterion value (RVL3) (S52). It is determined that a manner in which the vehicle performance test is conducted satisfies a performance condition when, in all the speed regions (LVR, MVR, HVR), a calculated value (OR) related to the selection criterion value is greater than or equal to a threshold (S53: YES) (S56).
