Abstract
Official abstract text for this publication.
A porous metal body including a skeleton having a three-dimensional mesh-like structure, the porous metal body having a plate-like overall shape. The skeleton has a hollow structure and includes a primary metal layer and at least one of a first microporous layer and a second microporous layer. The primary metal layer is composed of nickel or a nickel alloy. The first microporous layer contains nickel and chromium and is disposed on the outer peripheral surface of the primary metal layer. The second microporous layer contains nickel and chromium and is disposed on the inner peripheral surface of the primary metal layer, the inner peripheral surface facing the hollow space of the skeleton.
First claim
Opening claim text (preview).
The invention claimed is: 1. A porous metal body including a skeleton having a three-dimensional mesh-like structure, the porous metal body having a plate-like overall shape, the skeleton having a hollow structure, the skeleton comprising a primary metal layer a first microporous layer and a second microporous layer, the primary metal layer being composed of nickel or a nickel alloy, the first microporous layer containing nickel and chromium, the first microporous layer being disposed on an outer peripheral surface of the primary metal layer, the second microporous layer containing nickel and chromium, the second microporous layer being disposed on an inner peripheral surface of the primary metal layer, the inner peripheral surface facing a hollow space of the skeleton. 2. The porous metal body according to claim 1 , wherein the content of chromium in the porous metal body is 20% by mass or more and 50% by mass or less. 3. The porous metal body according to claim 1 , wherein the overall shape of the porous metal body has a thickness of 0.2 mm or more and 1.2 mm or less. 4. The porous metal body according to claim 1 , wherein the porous metal body has a porosity of 51% or more and 90% or less and a metal-coating weight of 200 g/m 2 or more and 1200 g/m 2 or less.
