Given an ellipse $C:\frac{{{x}^{2}}}{{{a}^{2}}}+\frac{{{y}^{2}}}{{{b}^{2}}}=1\left( a > b > 0 \right)$ with left and right focal points ${F}_{1},{F}_{2}$, and a point $P\left( 1,\frac{\sqrt{2}}{2} \right)$ on the ellipse such that $\vert P{F}_{1}\vert+\vert P{F}_{2}\vert=2 \sqrt{2}$.

(1) Find the standard equation of the ellipse $C$.
(2) A line $l$ passes through ${F}_{2}$ and intersects the ellipse at two points $A$ and $B$. Find the maximum area of $\triangle AOB$.
