Provided are a legume containing high concentrations of zinc in the grains, and a method for producing the same. Provided are also grains of a legume, except adzuki bean, containing 5.5 mg/100 g or more of zinc, and a method for producing a legume containing 4.0 mg/100 g or more of zinc in the grains, the method including spraying a solution containing zinc at a concentration of 0.01 to 2% by weight, on the leaves or the raceme regions, starting from the flower bud stage of the legume.

A method for producing a stainless steel three-ply clad sheet for a fuel cell separator comprises heating a source blank and then performing rough rolling, hot rolling and cold rolling thereto, whereby the clad steel sheet for the fuel cell separator or a solid polymer type fuel cell separator thereby is obtained. The source blank for the clad steel sheet is composed of a stainless steel utilizing 0 to 0.3% B as a core component and a stainless steel containing 0.3 to 2.5% B as face component. The source blank is made using face components, a core component, tabs and protectors and performing steps including bonding of the tabs and protectors to the face components, removing portions of the tabs and protectors, piling of the face components to the core component, and further bonding of the face and core components together to form the source blank.

A stainless steel slab containing B, wherein a protecting material is joined onto at least two faces across the bloom from each other in a stainless steel bloom containing B of 0.3&#x2013;2.5 mass %, being integrated into one-piece by forming a weld metal comprising a stainless steel with chemical composition that satisfies the relationship expressed by following formulas (1)&#x2013;(4), and a method to produce a steel product by rolling said slab. Further, it is preferable to interpose an insert material between above stainless steel bloom and above protecting material in bonding process.15&#x2266;Cr,&#x2003;&#x2003;(1)4&#x2266;Cr&#x2212;Ni&#x2266;17,&#x2003;&#x2003;(2)Cr=Cr+1.5 Si+Mo&#x2212;5 B,&#x2003;&#x2003;(3)Ni=Ni+30 (C+N)+0.5 Mn&#x2003;&#x2003;(4) Herein, each symbol of a chemical element designates the content (mass %) of relevant chemical element contained in steel. Accordingly, it makes it possible to subject a stainless steel slab containing B to hot working without generating edge cracking, so as to be used as a source material of a neutron shielding container and a separator of a fuel cell.
