摘要： Based on an operation condition φ(t) of a polymer electrolyte fuel cell at a time t, the concentration distribution of a radical generation ion and the concentration distribution of a radical scavenging ion in an electrolyte membrane are estimated. Next, a load command p(t+Δt) at a time (t+Δt) is acquired. Next, a reference operation condition φref(t+Δt) under which the load command p(t+Δt) can be realized is acquired. Next, whether or not a judgment index exceeds a first threshold value ϵ1 is judged. When the judgment index exceeds ϵ1, an operation condition which is different from φref(t+≢t) and gives the judgment index of ϵ1 or less is selected as φ(t+Δt). On the other hand, when the judgment index does not exceed ϵ1, φref(t+Δt) is selected as φ(t+Δt). The fuel cell system has a control device for performing such treatments.

摘要： An object provides a power generation apparatus performing the purification of an Al alloy melt using scrap as raw material. A power generation apparatus includes: a container body with aluminum alloy melt and molten salt in a liquid junction with the aluminum alloy melt; an anode which is in contact with the aluminum alloy melt; and a cathode which is in contact with the molten salt. DC power is obtained from between the anode and the cathode by an anode reaction on the aluminum alloy melt side and a cathode reaction on the molten salt side. When the aluminum alloy melt and the molten salt are separated by a separator allowing ionic conduction between the aluminum alloy melt and molten salt, the power generation efficiency is enhanced. The amount of a reactant in the Al alloy melt is monitored by measuring the electrical quantity associated with the power generation.

摘要： A detection device for detecting a status of a lithium-ion secondary battery includes a control module that acquires real part of AC impedance at a frequency at which the real part of the AC impedance is increased 10 times or more than the real part of the AC impedance at 1 kHz due to a skin effect, and detects deposition of lithium and/or the presence of foreign metal inside the lithium-ion secondary battery by using the acquired real part of the AC impedance.

摘要： A novel spot welding method for steel sheets and an aluminum alloy sheet, includes stacked sheet materials from a pair of opposing electrodes to join the sheet materials by resistance heating. The pair of opposing electrodes are in pressure contact with both outer surfaces of the sheet sets. The sheet sets include at least a first and second steel sheet, and an aluminum alloy sheet stacked in this order. A first energization step forms a molten pool between facing surfaces of the first and second steel sheets without melting the aluminum alloy sheet. A second energization step causes a melting reaction between facing surfaces of the second steel sheet and the aluminum alloy sheet. The first and second steel sheets are joined via a first nugget. The second steel sheet and the aluminum alloy sheet are joined via a second nugget including an intermetallic compound generated by the melting reaction.

摘要： A metal joined body has an iron base body and an aluminum base body that are joined together via a joint layer. The joint layer has a first layer composed of a first intermetallic compound formed on the iron base body side and a second layer composed of a second intermetallic compound formed on the aluminum base body side. The first layer has one or more first protrusions that merge integrally into the iron base body and extend in a pile shape into the first intermetallic compound. The second layer may have one or more second protrusions that are composed of a second intermetallic compound and extend in a columnar shape into the aluminum base body. The first intermetallic compound may contain Al5Fe2, and the second intermetallic compound may contain Al3Fe. The total thickness of the first layer and the second layer is, for example, 2 to 15 μm.

摘要： A method with which Mg can be removed from aluminum alloy melt whose raw material is scrap or the like. Metal removal method includes processing step of forming molten salt layer in contact with aluminum alloy melt containing Mg which covers at least part of the surface of the aluminum alloy melt. This method allows Mg to be taken in from aluminum alloy melt to molten salt layer and removed. Molten salt layer contains specific halogen element that is one or more of Cl or Br and specific metal element that is one or more of Cu, Zn, or Mn. The specific metal element is supplied as an oxide of the specific metal element to the molten salt layer. At that time, the molten salt layer contains Mg. The step of removing Mg is performed by disposing a conductor that bridges the aluminum alloy melt and the molten salt layer.
